Pietro CampagnanoandClaude Sonnet 4.6 15ea7027df style: move file type badges into Type column (#1793) 
## Summary

The file type was shown twice in the file browser table: as a bold badge
in the **Name** column and as plain text in the **Type** column.

**Before:** badge in Name column + redundant text in Type column
**After:** badge lives exclusively in the Type column

| | Before | After |
|---|---|---|
| Folder | Name: `📁 folder` **FOLDER** · Type: `Folder` | Name: `📁
folder` · Type: **FOLDER** |
| EPUB | Name: `📗 book.epub` **EPUB** · Type: `EPUB` | Name: `📗
book.epub` · Type: **EPUB** |
| Other | Name: `📄 file.txt` · Type: `TXT` | unchanged |

src="https://github.com/user-attachments/assets/f9fb2898-b165-478a-813b-f2290ad3e42c"
/>


## Changes
- Removed `epub-badge` and `folder-badge` from the Name column
- Moved badges into the Type column, replacing the redundant plain text
- Non-EPUB files are unaffected (extension text remains in Type column)

Zach Nelson b25389b43e refactor: Move language setting into JSON settings (#1796) 
## Summary

Another follow up to #1408. That PR revised the language.bin settings
file to version 2. After merging, it occurred to me that it would make
more sense to have the language inside the overall settings.json file,
easy for users to see and change directly.

This change adds migration from language.bin to settings.json. It only
migrates from the pre-#1408 v1 language.bin format, because v2 has only
been in for a couple of commits and I don't think we need long-term
maintenance code to handle it.

#1408 had a potential long-term maintenance issue for migration. It
assumed that the enum order of languages never changes, only grows. So,
e.g. "Portuguese (Portugal)" could never be added next to "Portuguese
(Brazil)", only appended. This change includes a hardcoded frozen
ordering of the language indices as they existed at 2f969a9, and
migrates to storing a language code string in the settings.json instead
for future reordering flexibility.

Similar to the settings.bin to settings.json migration, which renames
settings.bin to settings.bin.bak, this change renames language.bin to
language.bin.bak after adding the language setting to settings.json.

Jon Stieglitz 2f969a93b4 feat: context-aware screenshot filenames with book title (#1589) 
## Summary

I love the new screenshot feature but I can tell that soon I'm gonna
have a folder full of screenshots and not know what's what. It would be
great if the folder could self organize.

When a screenshot is taken while reading, the filename would now include
the book title, chapter (EPUB), page number, and progress percentage.

Example: My-Great-Book_ch3_p5_42pct_12345.bmp

* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
* **What changes are included?**

## Additional Context

* Non-reader screens keep the existing screenshot-<millis>.bmp naming.

spfenwick bc9651b664 fix: use same file name as KOReader for OPDS downloads (#1286) 
This allows KOSync to work for files downloaded from OPDS when set to
use filename matching

## Summary

* **What is the goal of this PR?** Brings the names of files downloaded
via OPDS into line with the KOReader OPDS plugin so the files sync when
KOSync is set to filename matching
* **What changes are included?** Change the filename generated by the
OPDS browser from "\<title\> - \<author\>" to "\<author\> - \<title\>"
so it matches KOReader.

## Additional Context

* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
  specific areas to focus on).

Both KOReader and crosspoint sanitise the filename by removing special
characters. This step seems to already use the same rules.

pablohc 907e14da28 fix: pressing space barely moves input cursor (#1729) (#1733) 
## Summary

* **What is the goal of this PR?** 
Fix the visual keyboard cursor not advancing when typing a space. Typing
one space leaves the cursor at position 0; typing two spaces advances it
only by one space width. This affects all input types except URL.
* **What changes are included?** 
Replace `getTextWidth()` with `getTextAdvanceX()` in four locations
within `KeyboardEntryActivity::render()` for cursor positioning and
line-wrapping calculations.

## Additional Context

* **Root cause**: `getTextWidth()` returns the bounding-box width of the
drawn glyphs. The space glyph has `width=0` and `height=0` (it's
invisible), so `getTextWidth(" ") == 0`. The trailing `advanceX` of the
last character is only flushed when the *next* character is processed,
so a string ending in space reports zero width. `getTextAdvanceX()`
correctly includes the final glyph's advance, matching how `drawText()`
actually positions characters.

Arthur TazhitdinovandCopilot 1cf2239742 feat: Support for multiple OPDS servers (#1209) 
## Summary

* Add support for configuring and using multiple OPDS servers, replacing
the previous single-server limitation. Closes
https://github.com/crosspoint-reader/crosspoint-reader/issues/1178
* New OpdsServerStore singleton (modeled after WifiCredentialStore) that
persists up to 8 OPDS servers to /.crosspoint/opds.json with MAC-based
password obfuscation.
* One-time migration from legacy single-server fields in
CrossPointSettings to the new store on first boot.
* New OpdsServerListActivity for the device UI — works in two modes: a
settings list (add/edit/delete servers) and a picker (select which
server to browse). When only one server is configured, the picker is
skipped automatically.
* Renamed CalibreSettingsActivity → OpdsSettingsActivity for clarity. It
now edits individual OpdsServer entries (name, URL, username, password,
delete).
* OpdsBookBrowserActivity now receives an OpdsServer at construction and
uses its credentials for all fetches/downloads, and shows the server
name in the header.
* HttpDownloader::fetchUrl and downloadToFile accept optional per-call
username/password parameters instead of reading from global settings.
* REST API endpoints on CrossPointWebServer: GET /api/opds, POST
/api/opds, POST /api/opds/delete — passwords are never exposed over the
API (only a hasPassword flag), and omitting the password field on update
preserves the existing one.
* Web UI (SettingsPage.html) with dynamic OPDS server management cards —
add, edit, save, and delete servers from the browser.
<img width="932" height="906" alt="SCR-20260416-stvu"
src="https://github.com/user-attachments/assets/a8f18d84-4204-46a0-bb31-b73d24b3255f"
/>


## Additional Context

* The OpdsServerStore JSON format and obfuscation scheme are identical
to WifiCredentialStore, so the same JsonSettingsIO infrastructure
handles both.
* The web API uses POST /api/opds/delete instead of DELETE /api/opds
because the ESP32 WebServer doesn't support the DELETE method with a
request body.
* Existing single-server configurations are migrated automatically — no
user action required. After migration the legacy CrossPointSettings
fields are cleared so it only runs once.
* The HttpDownloader changes are backward-compatible: the credential
parameters default to empty strings, so existing callers are unaffected.

Pietro CampagnanoandClaude Sonnet 4.6 867fb7cbe2 style: unify page headers across web UI (#1702) 
## Summary

* **Goal**: Align `FilesPage` and `SettingsPage` headers with the
existing `HomePage` pattern.
* **Changes**:
- Added `<h1>📚 CrossPoint Reader</h1>` at the top of `<body>` on both
pages.
- Demoted the page-specific `📁 File Manager` heading on `FilesPage` from
`<h1>` to `<h2>` (inside `.page-header`), so every page has a single
`<h1>` — the app name.
- Moved the accent-colored `border-bottom` from `.page-header` to `h1`,
matching the HomePage CSS.

All three pages now share the same top structure:
`<h1>CrossPoint Reader</h1>` → nav links → page content.

## Screenshots

### Home

**Before and after is the same**
<img width="1153" height="388" alt="home before"

/>



## Additional Context

* Pure markup + CSS, no JavaScript or behavioral changes.
* Improves HTML semantics (single `<h1>` per page, referring to the
app).
* No new CSS duplication introduced — borrows existing styling from
HomePage.

Instead of having a fixed maxwidth in pixels for subtitle, it will use
the whole line and shorten the longest one if needed.

So instead of: <img width="480" height="140" alt="image"
src="https://github.com/user-attachments/assets/67e4777b-10d0-4a05-b5c7-fb775776c186"

Pietro Campagnano 9dab5f471b style: put page name first in browser titles (#1703) 
## Summary

* **Goal**: Make browser tab titles, bookmarks, and history entries
distinguishable across pages (including individual folders in the File
Manager).
* **Changes**:
- Reordered `<title>` so the page name comes first, followed by
`CrossPoint Reader`. Browser tabs usually truncate titles from the
right, and bookmark/history lists are sorted alphabetically by title —
putting the differentiating part first keeps it visible in both cases,
instead of every entry starting with `CrossPoint Reader - …`.
- On `FilesPage`, added a small JS hook that updates `document.title`
with the current subfolder leaf when a `path` query parameter is present
— previously all folders shared the same title.

| URL | Title before | Title after |
|-----|--------------|-------------|
| `/` | `CrossPoint Reader` | `CrossPoint Reader` _(unchanged)_ |
| `/settings` | `CrossPoint Reader - Settings` | `Settings - CrossPoint
Reader` |
| `/files` | `CrossPoint Reader - Files` | `Files - CrossPoint Reader` |
| `/files?path=/Books` | `CrossPoint Reader - Files` | `Books - Files -
CrossPoint Reader` |
| `/files?path=/Books/Fantasy` | `CrossPoint Reader - Files` | `Fantasy
- Files - CrossPoint Reader` |

## Additional Context

* Pure client-side change: `<title>` tags plus ~3 lines of JavaScript on
FilesPage. No network, behavior, or memory impact.
* The static `<title>` tag remains as a fallback if JS fails.
* `HomePage` title left as-is since the app name alone is the standard
convention for a root/home page.

Pietro CampagnanoandClaude Sonnet 4.6 e28918b24d fix: pluralize folder/file counts correctly in file list summary (#1701) 
## Summary

* **Goal**: Fix incorrect pluralization in the file manager web UI
summary line.
* **Changes**: `FilesPage.html` always rendered the plural forms
("folders"/"files") regardless of count. The summary now selects
singular or plural based on each count.

Example:
- Before: `1 folders, 1 files, 12 KB`
- After: `1 folder, 1 file, 12 KB`

## Additional Context

* Cosmetic-only fix — no behavior, performance, or memory impact.
* Change is fully client-side (JavaScript inside a single HTML
template).
* English-only; web UI localization is out of scope here.

Brandon PhilipsandClaude Sonnet 4.6 c0ee096841 fix: relative opds paths and query param with copyparty (#1535) 
## Summary

* **What is the goal of this PR?**

This PR fixes bugs when using Copyparty as an OPDS server. 

https://github.com/9001/copyparty?tab=readme-ov-file#opds-feeds

OPDS uses a query parameter `?opds` to differentiate between HTML
requests and OPDS requests for the same path. It also uses relative
paths in the responses instead of full paths. Crosspoint didn't handle
these two cases.

* **What changes are included?**

Fixes to the two issues above.

## Additional Context

* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
  specific areas to focus on).

Here is some example XML from my Copyparty instance:

pablohc 1a145fe085 fix: keyboard feedback #1644 (#1697) 
Addresses reviewer feedback from #1644:
- **Localize keyboard hint strings** — 13 hardcoded English strings
replaced with \`tr()\` macro (\`STR_KB_HINT_*\`), making them
translatable across all 22 languages (fallback to English when not yet
translated)
- **Deduplicate \`Lyra3CoversMetrics\`** — now derives from
\`LyraMetrics\` via lambda copy, overriding only \`homeCoverTileHeight\`
and \`homeRecentBooksCount\` (eliminates ~30 duplicated metric fields)
- **Unify keyboard drawing in \`BaseTheme\`** — \`drawTextField\` and
\`drawKeyboardKey\` overrides removed from \`LyraTheme\`; variability
controlled via \`keyboardKeyCornerRadius\` metric (0=Base, 6=Lyra).
Unified text field padding to 6, adopted Lyra's secondary label draw
order (main first, then secondary)
- **Add URL-optimized keyboard layout** — \`urlLayout\` with \`:\` and
\`/\` replacing \`=\` and \`,\` for easier URL input without switching
to SYM mode

Zach Nelson 64f5ef018a feat: Support for proportional numeral spacing (#1414) 
## Summary

**What is the goal of this PR?**

Reading a book with frequent numbers, I noticed that the spacing between
numeral glyphs was strangely large. This was because Bookerly and Noto
Sans default to tabular figures, where every digit gets an identical
advance width. This is designed for column alignment in spreadsheets,
but in rendering prose it produces visually wide gaps between digits.

This change adds a `--pnum` flag to fontconvert.py that applies the
font's OpenType `pnum` (proportional numerals) feature during
conversion. When active, the converter:
- Parses the GSUB table for pnum SingleSubst lookups
- Resolves substitute glyph indices via fonttools' glyph order
- Loads the proportional alternate glyphs instead of the tabular
defaults
- Includes substitute glyph names in kern pair extraction, so kerning
data that references proportional alternates is captured

Bookerly's proportional alternates also carry digit-digit and
digit-punctuation kerning that the tabular glyphs lack (e.g., at 16pt
7->4 at -1.69px, 7->. at -2.31px, 7->1 at +1.00px).

Noto Sans gains proportional advances but no new kerning (its
proportional glyphs have no kern class data in the font).

OpenDyslexic is unaffected. Its `cmap` already points to proportional
glyphs, so `--pnum` is a no-op. `--pnum` is intentionally omitted from
OpenDyslexic in the build script for deliberately uniform digit spacing
as an accessibility choice.

UI fonts (Ubuntu, notosans_8) also omit `--pnum` to preserve tabular
alignment for page numbers, battery percentages, etc.

## Changes

### Layout (10-column uniform grid)
- Reduced from 13/11/10 columns per row to **10 uniform columns** across
all rows
- Keyboard now uses **90% of screen width** (was ~66%)
- Row 0: Numbers `1-9, 0` with secondary symbols (`!@#$%^&*()`)
- Rows 1-3: Standard QWERTY letters
- Bottom row: `shift` | `#@!` | `___` | `←` | `OK`

### New Symbol Mode (#@!)
- New mode toggle key `#@!` / `abc` switches between letter and symbol
layouts
- Symbol layout: 4 rows (numbers, inverted symbols, paired symbols,
loose symbols)
- Covers all 95 printable ASCII characters
- **No secondary hints, no long-press** in symbol mode (simple and
direct)
- SHIFT key remains visible but **disabled** in symbol mode

### URL Mode
- In `InputType::Url`, the Space key becomes a **URL toggle** button
- Activating URL mode replaces the 4 content rows with a **3×3 grid of
URL snippets**:
  - Col 0 (protocols): `https://`, `http://`, `/opds`
  - Col 1 (hosts/ports): `www.`, `192.168.`, `:8080`
  - Col 2 (domains): `.com`, `.org`, `.net`
- Snippets are inserted as full strings at the cursor position
- URL mode **persists** after inserting a snippet (does not
auto-deactivate)
- Column alignment: col 0 over ABC, col 1 over URL, col 2 over Del
- Up/Down navigation maps `bottomCol - 1` / `urlCol + 1`
- SHIFT disabled in URL mode
- SpecMode (`abc`) exits URL mode back to ABC
- SpecSpace (`URL`) toggles URL mode on/off; selection always stays on
the URL button
- Button styled with `KeyboardKeyType::Mode` for consistent outline

### Cursor Mode
- **Enter**: Long-press Up (500ms) while in keyboard mode
- **Exit**: Short-press Down while in cursor mode (resets
`passwordVisible`, clears toggle position)
- **Navigate**: Left/Right move cursor position within text (one
position per press, no continuous repeat)
- **Visual**:
  - Keyboard mode: underline cursor (2px line + serifs)
  - Cursor mode: inverted block cursor (black fill + white character)
- Block width adapts to the actual character width under cursor (minimum
6px for narrow chars like space)
- Block position includes inter-character kerning offset for correct
alignment (calculated via string-difference: `getTextWidth(before+char)
- getTextWidth(before) - getTextWidth(char)`)
  - End-of-text: thin 6px block
- Password hidden: 3-part drawing (Part 1 + block + Part 3) to prevent
block overflow onto `*` characters
- Toggle position: caret ("I") cursor at saved position, `[abc]`/`[***]`
label with inverted selection
- **Inactive key styling**:
  - BaseTheme: 2px outline rectangle
  - LyraTheme: gray filled rounded rectangle (`Color::LightGray`)
- **Password toggle position**: in cursor mode (Password only), Hold
Right (500ms) enters toggle — caret cursor shows saved position,
`[abc]`/`[***]` label becomes selected. Press Confirm to toggle
`passwordVisible`. Press Left to restore cursor to saved position. Right
from toggle is a no-op. Down from toggle exits to keyboard.
- `cursorPos` persists between keyboard and cursor modes

### Password Mode
- `InputType::Password` enum replaces `bool isPassword` parameter
- Text is masked with `*` except for one revealed character:
  - Keyboard mode: reveals character at `cursorPos - 1`
- Cursor mode: no reveal in display text (block cursor draws actual char
directly)
- **Toggle `[abc]`/`[***]`**: accessible via cursor mode — Hold Right
(500ms) enters toggle position, Confirm toggles visibility, Left exits
back to cursor. Caret ("I") shown at saved position while in toggle.
- `passwordVisible` resets to `false` when exiting cursor mode
- **Long-press Del (1.5s)**: clears all text and resets cursor to 0

### InputType Enum
- Replaced `bool isPassword` constructor parameter with `enum class
InputType { Text, Password, Url }`
- Callers updated: `WifiSelectionActivity`, `KOReaderSettingsActivity`,
`CalibreSettingsActivity`

### Contextual Tips
- `"Tips:"` header followed by context-sensitive hints, centered between
text field underline and keyboard as a block
- ABC mode: `"Hold SELECT for UPPERCASE or secondary char"` (shift ON:
`"lowercase"` variant) + `"Hold DEL to clear all text"` (only if text
not empty)
- ABC + `InputType::Url`: same + `"Press URL for snippets"`
- Symbol mode: `"Hold DEL to clear all text"` (only if text not empty)
- URL mode: `"Press ABC to exit URL mode"` + `"Hold DEL to clear all
text"` (only if text not empty)
- Cursor mode: `"Press DOWN to return to keyboard"`

### Hint Phases (cursor mode, Password only)
- **Phase 1**: `"Hold UP to edit entry"` — shown after 2× DEL press,
auto-hides after 4s, positioned below underline
- **Phase 2**: `"Press < or > to move cursor"` + dynamic password toggle
hint — shown when entering cursor mode, positioned below underline,
visible until exit
- When `!passwordVisible`: `"Hold > then press [abc] to show password"`
  - When `passwordVisible`: `"Hold > then press [***] to hide password"`
  - When in toggle position: `"Press < to return to cursor position"`

### Long-Press Alternative Character
- Holding Confirm (>500ms) inserts the **alternative character** instead
of the primary
- Letters: long-press inserts opposite case (e.g., `a`→`A`, `A`→`a`)
- Numbers/symbols (row 0): long-press inserts secondary (e.g., `0`→`)`,
`)`→`0`)
- Only active in ABC mode; disabled in Symbol mode and URL mode
- **`InputType::Url`**: Hold SELECT on ABC rows 1+ (letters) returns
primary character only (same as short press). Row 0 (symbols) still
returns secondary character on Hold SELECT.

### Shift (2 sticky states)
- Reduced from 3 states (shift/SHIFT/LOCK) to **2 sticky states**
(shift/SHIFT)
- Shift stays active after typing until manually toggled off
- Label: `shift` (off) / `SHIFT` (on)

### SpecialKeyType Enum
- `enum class SpecialKeyType { Shift, Mode, Space, Del, Ok }` replaces
plain `enum` (`SpecShift`, `SpecMode`, etc.) for type safety
- All switch cases updated to `SpecialKeyType::*` with
`static_cast<int>()` for array indexing
- `onExit()` reverted to simple `Activity::onExit()` call (half-refresh
removed)
- **Bottom row column mapping**: navigating up/down between content rows
and bottom row uses `col/2` and `col*2` formulas for consistent
positioning (10 cols ↔ 5 cols)
- **URL mode column mapping**: `bottomCol - 1` / `urlCol + 1` (3 cols ↔
5 cols)
- **Wrap-around**: row 0 → up → bottom row and bottom row → down → row 0
both apply correct column mapping

### Visual Improvements (both Base and Lyra themes)
- **Space key**: underscore-style horizontal line (60% of key width, 3px
thick)
- **Delete key**: arrow `←` drawn with lines (3px thick) instead of
"DEL" text
- **Secondary label** (ABC row 0): small hint in top-right corner with
separation from primary number
- **BaseTheme**: selection uses **inverted fill** (black rect + white
text) instead of `[bracket]` markers
- **BaseTheme**: text field brackets drawn as **stretchable lines** that
adapt to multi-line input (1px normal, 3px cursor mode)
- **LyraTheme**: text field uses **fixed-width underline** (16px
margins, 8px each side) instead of stretchable line (2px normal, 3px
cursor mode)
- **Both themes**: special keys (shift, mode, space, del, OK) have
bordered/bordered-rounded rectangles
- **Font size**: keyboard uses `UI_12_FONT_ID` in both themes (was
`UI_10` in Base)
- **Key height**: 40px in all themes for better proportions
- **Layout unification**: text and password toggle are left-aligned in
all themes (`keyboardCenteredText = false` for Lyra/Lyra3Covers)
- **`primaryOffset` removed**: dead code eliminated from BaseTheme and
LyraTheme `drawKeyboardKey`

### New Theme Metrics
- `keyboardVerticalOffset`: per-theme vertical adjustment of keyboard
position
  - Base: `-13`, Lyra: `-7`
- `keyboardBottomKeySpacing`: independent spacing for bottom row keys
  - Base: `5`, Lyra: `5`
- Bottom-aligned keyboard in both themes for consistent vertical
positioning
- Bottom row total width calculated to match content rows width (10-col
based, consistent across modes)
- 4px extra gap between content rows and bottom row when `bkSpacing > 0`
- `keyboardCenteredText`: `false` for all themes (unified left-aligned
text)

### Defensive Improvements
- **State reset on re-entry**: `onEnter()` resets all mutable state
(`symMode`, `urlMode`, `cursorMode`, `togglePos`, `passwordVisible`,
`shiftState`, `selectedRow`, `selectedCol`, `rightHeld`,
`rightLongHandled`, `savedCursorPos`, `rightStartCursorPos`,
`delPressCount`, `hintVisible`, `hintShowTime`) — prevents stale state
when re-entering the keyboard
- **Bounds checking**: `insertChar`/`insertString` clamp `cursorPos` to
`text.length()` before inserting
- **Empty string guard**: `insertString` returns early on empty string
- **`std::string::npos`**: used instead of `SIZE_MAX` for size_t
sentinel (proper C++ idiom)
- **`<algorithm>` header**: included for `std::max`

### Toggle Position
- [x] Hold Right > 500ms in cursor mode (Password) → enters toggle,
caret visible at saved position
- [x] Short-press Right in cursor mode (Password) → advances cursor 1
position, does not jump to toggle
- [x] Short-press Left in cursor mode (Password) → moves cursor left 1
position, from toggle returns to saved position
- [x] Confirm in toggle → toggles `passwordVisible`
- [x] Left from toggle → returns to saved position, caret disappears,
block cursor appears
- [x] Right from toggle → no-op
- [x] Down from toggle → exits to keyboard, cursor at saved position
- [x] Hold Right in cursor mode (InputType::Text) → no effect
- [x] Hold Right in cursor mode (InputType::Url) → no effect
- [x] Hold Right < 500ms released in cursor mode (Password) → short
press, advances cursor 1
- [x] No continuous repeat when holding Left or Right in cursor mode

### Caret Visual in Toggle
- [x] In toggle: caret "I" visible at saved cursor position

- [x] Phase 1 auto-hides after 4s
- [x] Phase 2 appears when entering cursor mode ("Press < or > to move
cursor")
- [x] Phase 2 shows "Hold > then press [abc] to show password" when
`!passwordVisible`
- [x] Phase 2 shows "Hold > then press [***] to hide password" when
`passwordVisible`
- [x] Phase 2 shows "Press < to return to cursor position" when in
toggle
- [x] Phase 2 disappears when exiting cursor mode

### Long-Press `InputType::Url` Behavior
- [x] Hold SELECT on letter rows (rows 1+) with InputType::Url → same
character as short press
- [x] Hold SELECT on row 0 with InputType::Url → secondary character
works normally

### Number Row Reorder
- [x] Number row order: 1-9, 0 left to right
- [x] `(` and `)` are adjacent (positions 8 and 9) via secondary labels
- [x] Long-press on row 0 returns correct secondary symbols in new order

offset applied)
- [x] Block cursor correctly positioned for mixed characters (letters,
numbers, symbols)
- [x] Block width minimum 6px for narrow characters (space) — visible as
block, not thin line
- [x] Password hidden: 3-part drawing prevents block overflow onto `*`
characters
- [x] Password visible: block post-loop draws correctly on continuous
text (no 3-part needed)
- [x] End-of-text block: thin 6px block at correct position

### Integration
- [x] WiFi password entry (connect to network)
- [ ] KOReader username, password, and sync server URL
- [ ] Calibre OPDS URL, username, and password
- [ ] Calibre OPDS URL: empty → opens with "https://" prefilled
- [ ] Calibre OPDS URL: type "http://" or "https://" only → saved as
empty
- [ ] Calibre OPDS URL: type full URL → saved correctly
- [ ] Calibre OPDS URL: existing URL → opens with existing URL (not
"https://" prefill)

zgredexandPatryk Radtke c4f5c8e931 fix: prevent wallpaper clustering with 16-entry recency buffer (#1606) 
## Problem

Custom sleep wallpapers feel repetitive — the same image appearing
multiple times in a short session. Only the single most-recently-shown
index was stored (`uint8_t lastSleepImage`), so on collections of 3–5
images, two-pick cycles were common. On larger collections, any image
could reappear within the next few picks.

## Solution

Add a 16-entry circular recency buffer to `CrossPointState` that
excludes recently shown wallpapers from selection.

**Recency buffer** (`recentSleepImages[16]`, `recentSleepPos`,
`recentSleepFill` — 34 bytes DRAM):
- Tracks the last 16 shown wallpaper indices
- On each pick, rerolls up to 20 times if the candidate was recently
shown
- Window auto-shrinks to `numFiles - 1` for small collections
(guarantees a non-repeat is always possible)
- `isRecentSleep()` clamps to `recentSleepFill` to avoid false positives
on unwritten buffer slots
- State persisted to `state.json` so the buffer survives sleep/wake
cycles

**Migration**:
- Binary (`state.bin`): old `lastSleepImage` field seeded into the new
buffer if valid
- JSON (`state.json`): legacy `lastSleepImage` key detected and seeded
into the buffer when upgrading from older firmware

## Index type fix

`randomFileIndex` upgraded from `uint8_t` to `uint16_t` — silently
truncated for collections larger than 255 wallpapers.

## Repeat probability: before vs after

Chance of seeing a recently-shown image on the next pick. After:
`(numFiles - 16) / numFiles` once collection exceeds the window; 0%
while ≤17.

| Collection | Before | After |
|---|---|---|
| 3 | 50% | 0% |
| 5 | 75% | 0% |
| 10 | 89% | 0% |
| 17 | 94% | 0% |
| 18 | 94% | 6% |
| 20 | 95% | 20% |
| 25 | 96% | 36% |
| 30 | 97% | 47% |
| 50 | 98% | 68% |
| 100 | 99% | 84% |

## Memory impact

| Addition | Size |
|---|---|
| `recentSleepImages[16]` | 32 bytes DRAM |
| `recentSleepPos` + `recentSleepFill` | 2 bytes DRAM |
| **Total** | **34 bytes DRAM** |

## Files changed

- `src/CrossPointState.h` — recency buffer fields + `isRecentSleep()` /
`pushRecentSleep()` declarations
- `src/CrossPointState.cpp` — `isRecentSleep()` / `pushRecentSleep()`
implementations + binary migration path
- `src/JsonSettingsIO.cpp` — JSON serialisation of buffer state + JSON
migration
- `src/activities/boot_sleep/SleepActivity.cpp` — retry loop with
recency check

Егор Мартынов cced77783f feat: add orientation-aware popups for reader activities (#1428) 
## Summary

Make popups (like "Going to sleep") respect the current screen
orientation when shown from reader activities.

**What changes are included?**

- Apply reader orientation in SleepActivity before showing popup when
`lastSleepFromReader` is true
- Make popup Y-position proportional to screen height (7.5% for
BaseTheme, 16.5% for LyraTheme) instead of hardcoded pixel values,
ensuring correct positioning in both portrait and landscape modes.
- Add `isReaderActivity()` override to all reader sub-screens (menu,
chapter selection, percent selection, footnotes, QR display, KOReader
sync), so sleep popups rotate correctly when entering sleep from any
reader context.

Zach Nelson 1bd7a1de67 refactor: Deduplicate battery drawing code and fix Lyra charging indicator (#1437) 
## Summary

**What is the goal of this PR?**

Following up on #1427:
- Extracted shared battery drawing logic, including lightning bolt, to
reduce duplication.
- In Lyra with segmented battery the lightning bolt was hard to see, so
when charging Lyra now uses a solid battery fill.

Zach Nelson 23aad213fc refactor: Removed redundant FsFile close() calls (#1434) 
## Summary

**What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)

`DESTRUCTOR_CLOSES_FILE=1` is set in platformio.ini, which makes SdFat's
FsBaseFile destructor call close() automatically when a file goes out of
scope.

Three categories of file close calls remain untouched:
1. Close before Storage.remove() on the same path: ScreenshotUtil.cpp
closes the file before deleting it on write error. The remove might fail
if the file is still open.
2. Close before reopening the same variable: Epub.cpp writes a temp
NCX/nav file, closes it, then reopens it for reading. The
RecentBooksStore.cpp close before saveToFile() is the same pattern, it
rewrites the same file.
3. Close on member variables: BookMetadataCache.cpp (bookFile,
spineFile, tocFile), Section.cpp (file), XtcParser.cpp (m_file),
ZipFile.cpp (file). These persist beyond any single function scope, so
the destructor timing doesn't match the intended close point.

Diana 05f8e6e12d fix: webserver /delete API backward compatibility (#1475) 
## Summary

* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)

This fixes #682 by restoring API compatibility for external users, eg
deleting on-device books in bulk via calibre using the crosspoint plugin
works now.

* **What changes are included?**

The `/delete` webserver API now accepts the old `path` argument and maps
it to a JSON array element. It is made an error to provide both
arguments.

## Additional Context

* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
  specific areas to focus on).

I have compiled, flashed, and tested this on master at commit
0245972132. Before this change, calibre
cannot delete books, either individually or in bulk.

After this change, it can do so successfully.

## Summary

The cover/custom setting was a bit misleading to me. Usually after you
start reading a book you never see your customs again unless a cover
fails to render for some reason. With this, you can easily show your
custom images by just sleeping from the menus instead of the reader

 		fa2a3d2539 feat: add OPDS search support & next/prev page navigation (#1462) 
## Summary

**What is the goal of this PR?**
Adds OPDS search support, allowing users to search a catalog directly
from the book browser when the server exposes an OpenSearch template.

**What changes are included?**
- `OpdsParser`: parses the OpenSearch template URL from feed-level
`<link rel="search">` elements and exposes it via `getSearchTemplate()`
- `OpdsBookBrowserActivity`: fetches and stores the search template
after each feed load; shows a Search hint on the Left button when a
template is available; launches the existing `KeyboardEntryActivity` for
query input; URL-encodes the query and fetches the result feed
- Absolute search result URLs are handled correctly in `fetchFeed`
(skips prepending the server base URL)
- A `consumeConfirm` guard prevents the Confirm release that submits the
keyboard from immediately triggering a book download on the first
browsing frame after search results load

## Additional Context

- Search is silently unavailable if the server does not advertise an
OpenSearch template — no UI change in that case
- Tested against a Calibre-Web OPDS endpoint which exposes `<link
rel="search" type="application/opensearchdescription+xml">`
- The inline URL encoder in `performSearch` was necessary as
`StringUtils` has no such utility; worth considering extracting to
`StringUtils` in a follow-up
- No new dependencies introduced

Justinian 825ef56ad8 feat: X3 grayscale antialiasing improvements (#1607) 
## Summary
Improves text antialiasing quality on the Xteink X3 (SSD1677) display to
bring it closer to X4 rendering quality. Addresses white lines through
letter strokes and ghosting artifacts during page turns and screen
transitions.

## Changes

### Display Driver (open-x4-sdk)
- Dedicated X3 grayscale LUTs with tuned VDL drive strengths for dark
gray (2 time units) and light gray (3 time units), with active GND hold
on non-gray transitions to prevent floating source crosstalk
- Tight scan timing: TP2/TP3 reduced to 1 (total gate-on 7 units vs 17),
minimizing parasitic charge leakage that caused white lines through
letter strokes
- Fast diff BB reinforcement: Added mild VDH reinforcing pulse to
lut_x3_bb_full so black pixels are actively driven during differential
refreshes, clearing gray residue/ghosting
- displayGrayBuffer() updated to use the dedicated gray LUT bank instead
of full refresh LUTs for X3

### Rendering Pipeline
- Re-enabled light gray rendering for X3 text and images, now safe with
dedicated gray LUTs providing proper 4-level gray
- Removed isLightGrayRestricted() gating that was limiting X3 to 3-level
gray
- Runtime display dimensions in DirectPixelWriter and ScreenshotUtil,
replaced hardcoded constants with runtime getters to support X3 792x528
resolution

### Note
The open-x4-sdk submodule references a commit on
juicecultus/community-sdk. A corresponding PR to
open-x4-epaper/community-sdk should be merged first so the submodule ref
resolves on upstream.

## Testing
Tested on physical X3 hardware. White lines through letters
significantly reduced, in-book ghosting improved via BB reinforcement,
antialiasing visually closer to X4 quality.

## AI Disclosure
Yes, AI was used to assist with the development of these changes.

jpirnay ed0811c898 fix: Fix failing very first wifi connection attempt (#1521) 
## Summary

* **What is the goal of this PR?** The very first Wifi connection
attempt with saved credentials failed, subsequent attempts succeeded.
This PR fixes the first-attempt-issue.
* **What changes are included?**

## Additional Context
Claude analysis for WifiSelectionActivity

In attemptConnection() ,there's no WiFi.disconnect() before WiFi.begin()
— unlike the scan path earlier which does do a disconnect first.

The root cause on ESP32 is the built-in auto-connect feature: the ESP32
WiFi stack saves credentials to NVS flash and automatically starts
trying to connect on boot before your application code runs. When your
attemptConnection() then calls WiFi.begin(), the stack is already in a
transitional CONNECTING state, and the new begin() call either gets
ignored or collides with the in-progress attempt.

The fix is to add WiFi.disconnect(true) + a short delay in
attemptConnection() before calling WiFi.begin(), and optionally call
WiFi.persistent(false) to stop the ESP32 from auto-connecting on its
own.

Justin Mitchell 9b3885135f feat: Initial support for the x3 (#875) 
## Summary

Adds Xteink X3 hardware support to CrossPoint Reader. The X3 uses the
same SSD1677 e-ink controller as the X4 but with a different panel
(792x528 vs 800x480), different button layout, and an I2C fuel gauge
(BQ27220) instead of ADC-based battery reading.

All X3-specific behavior is gated by runtime device detection — X4
behavior is unchanged.

Depends on community-sdk X3 support: open-x4-epaper/community-sdk#19
(merged).

## Changes

### HAL Layer

**HalGPIO** (`lib/hal/HalGPIO.cpp/.h`)
- I2C-based device fingerprinting at boot: probes for BQ27220 fuel
gauge, DS3231 RTC, and QMI8658 IMU to distinguish X3 from X4
- Detection result cached in NVS for fast subsequent boots
- Exposes `deviceIsX3()` / `deviceIsX4()` helpers used throughout the
codebase
- X3 button mapping (7 GPIOs vs X4's layout)
- USB connection detection and wake classification for X3

**HalDisplay** (`lib/hal/HalDisplay.cpp/.h`)
- Calls `einkDisplay.setDisplayX3()` before init when X3 is detected
- Requests display resync after power button / flash wake events
- Runtime display dimension accessors (`getDisplayWidth()`,
`getDisplayHeight()`, `getBufferSize()`)
- Exposed as global `display` instance for use by image converters

**HalPowerManager** (`lib/hal/HalPowerManager.cpp/.h`)
- X3 battery reading via I2C fuel gauge (BQ27220 at 0x55, SOC register)
- X3 power button uses GPIO hold for deep sleep

### Display & Rendering

**GfxRenderer** (`lib/GfxRenderer/GfxRenderer.cpp/.h`)
- Buffer size and display dimensions are now runtime values (not
compile-time constants) to support both panel sizes
- X3 anti-aliasing tuning: only the darker grayscale level is applied to
avoid washed-out text on the X3 panel. X4 retains both levels via
`deviceIsX4()` gate

**Image Converters** (`lib/JpegToBmpConverter`, `lib/PngToBmpConverter`)
- Cover image prescale target uses runtime display dimensions from HAL
instead of hardcoded 800x480

### UI Themes

**BaseTheme / LyraTheme** (`src/components/themes/`)
- X3 button position mapping for the different physical layout
- Adjusted UI element positioning for 792x528 viewport

### Boot & Init

**main.cpp**
- X3 hardware detection logging
- Adjusted init sequence for X3 (no `HalSystem::begin()` dependency on
X3 path)

**HomeActivity**
- Uses runtime `renderer.getBufferSize()` instead of static
`GfxRenderer::getBufferSize()`

FYI I did not add support for the gyro page turner. That can be it's own
PR.

Zach Nelson 0cbfaa007d fix: Overlapping battery percentage on image pages with anti-aliasing (#1452) 
## Summary

**What is the goal of this PR?**

When viewing a page with images and anti-aliasing enabled, the
`imagePageWithAA` path renders the page twice with fast refreshes (blank
image area, then restore). Both passes called `renderStatusBar()`, which
reads the battery percentage live. If the value changed between the two
renders (e.g. 88% -> 87%), the digits would overlap on screen.
Fix: Removed the redundant `renderStatusBar()` from the second BW
render. The status bar is already drawn and displayed in the first pass,
and only the image area needs restoration.

pablohcandzgredex 7d56810ee6 feat: integrated epub optimizer (#1224) 
## Problem

Many e-ink readers have limited image decoder support natively.
EPUBs with images in other formats than **baseline JPEG** frequently
cause:

- **Broken images**: pages render as blank, corrupted noise, or never
load
- **Slow rendering**: unoptimized images cause severe delays on e-ink
hardware, up to 7 seconds per page turn, with cover images taking up to
59 seconds to render
- **Broken covers**: the book thumbnail never generates

Fixing this today requires external tools before uploading.

---

## What this PR does

Adds an **optional, on-demand EPUB optimizer** to the file upload flow.
When enabled,
it converts all images to baseline JPEG directly in the browser — no
server, no internet,
no external tools needed.

**Conversion is opt-in. The standard upload flow is unchanged.**

---

## Real-world impact

The optimizer was applied in batch to **61 EPUBs**:
- 60 standard EPUBs: 198 MB → 55 MB (**−72.2%**, 143 MB saved)
- Text-dominant books: 8–46% smaller (covers and inline images
converted)
  - Image-heavy / illustrated books: 65–93% smaller
- 1 Large manga volume (594 MB): 594 MB → 72 MB (**−87.8%**, 522 MB
saved)
- EPUB structural integrity fully maintained — zero new validation
issues introduced across all 61 books

*Size and integrity analysis:
[epub-comparator](https://github.com/pablohc/epub-comparator)*

From that set, **17 books were selected** as a representative sample
covering different content
types: image-heavy novels, pure manga, light novels with broken images,
and text-dominant books.
Each was benchmarked on two devices running in parallel, one on `master`
and one
on `PR#1224` — measuring render time across ~30 pages per book on
average.

## ⚠️ Known limitations

**KoReader hash-based sync will break** for converted files. The file
content changes,
so the hash no longer matches the original. Filename-based sync is
unaffected.

If you rely on KoReader hash sync, use the Calibre plugin or the web
tool instead.

## Build size impact

| Metric | master (53beeee) | PR #1224 (a2ba5db) | Delta |

|---------------|------------------|--------------------|----------------|
| Flash used | 5,557 KB | 5,616 KB | +59 KB (+1.1%) |
| Flash free | 843 KB | 784 KB | −59 KB |
| Flash usage | 86.8% | 87.7% | +0.9 pp |
| RAM used | 95,156 B | 95,156 B | no change |

> Both builds compiled with `gh_release` environment in release mode
(ESP32-C3, 6,400 KB Flash).
> The +59 KB increase is entirely due to `jszip.min.js` embedded as a
> gzipped static asset served from Flash. RAM usage is identical,
> confirming no runtime overhead — the library runs in the browser,
> not on the ESP32. ~784 KB of Flash remain available.

## Alternatives considered

| Approach | Friction |
|----------|---------|
| **This PR** — integrated in upload flow | Zero: convert + upload in
one step, offline, any browser |
| Calibre plugin (in parallel development) | Requires a computer with
Calibre installed, same network |
| Web converters | Requires extra upload / download / transfer steps |

LSTARandJake Kenneally 8dd365b4da feat: Implement silent pre-indexing for the next chapter in EpubReaderActivity (#979) 
## Summary

* A simple tweak to pre-index the next chapter silently during normal
reading.
* Triggers silent pre-indexing of the next chapter when the penultimate
page of a chapter is rendered to reduce visible interruptions.
* Keeps existing indexing with popup when a reader jumps directly into
an unindexed chapter.

## Additional Context

* Reader input is temporarily blocked during silent indexing to avoid
navigation/index state conflicts.
* The penultimate page is used because readers typically spend longer
there than on the final page.
* This change optimizes linear reading flow while preserving reliable
indexing for non-linear navigation.

## Possible Improvements

* Add a setting for First Page Indexing vs Penultimate Page Pre-indexing
* Display an indexing icon in the status bar instead of using a popup
that overlaps book text.

Tested on device:

## Summary

* **What is the goal of this PR?** All praise goes to @didacta for his
PR #537. Just picked up the reviewer comments to contain the changes as
suggested (there was no response for more than 6 weeks, so I wanted to
reanimate this feature).

Just one addition: should recognize usb cable plug ins / retractions and
update the icon immediately

* **What changes are included?**

## Additional Context

jpirnay 79b54b3a75 fix: Init lastSleepImage (edge case) (#1360) 
## Summary

* **What is the goal of this PR?** fix edge case for definition

## Additional Context

If loadFromFile() returns false (no state file exists — first boot, or
SD missing), lastSleepImage is never set and contains garbage.
[SleepActivity.cpp:83] then uses it in a while comparison to avoid
repeating the same image. The JSON path (doc["lastSleepImage"] |
(uint8_t)0) handles it, but only if the file exists.
