## Summary
It would be nice to switch back to the file list from an Reader activity
via a short back button press. This change adds an Reader option to
switch the default behavior, so a short back button press in the Reader
activity can now go back to the file list, and a long press on back goes
back to the home view. This does a fair bit of refactoring, introducing
a new constant for the ms limit.
* **What changes are included?**
- Changes to the translation
- Additional global Reader option
- Refactoring of the back button behavior in the Reader activity
Implements createUser() endpoint to allow account creation via the
KOSync protocol. Changes default sync server from sync.koreader.rocks to
sync.crosspointreader.com with migration logic to preserve existing
users' server settings. Extends sync protocol to include position data
(spine index, page numbers, xpath) that crosspoint-sync supports while
remaining compatible with standard kosync servers.
## Summary
Make KOReader progress sync a one-click flow for common cases while
keeping the existing manual mode available.
### Changes
- Add a **Sync Behavior** setting:
- **Smart sync** for new configurations
- **Ask every time** for manual control
- Preserve **Ask every time** when migrating an existing credential file
that predates this setting.
- In Smart mode:
- upload local progress when no remote record exists;
- show a short confirmation when already synced;
- upload when local progress is further ahead;
- apply remote progress when remote progress is further ahead.
- Probe both KOReader document-matching hashes before making the Smart
decision, while keeping uploads on the user's configured matching
method.
- Auto-return after successful Smart terminal states, with Back/Confirm
still available.
- Persist the setting alongside the current credential, matching-method,
and send-metadata fields.
- Document both behaviors in the user guide.
## Additional context
This pairs well with #2189 (smart Wi-Fi auto-connect), but does not
depend on it. It does not add background Wi-Fi or passive network
detection; sync is still triggered by the user from the reader menu.
Smart sync uses the furthest progress because CrossPoint does not
currently persist local progress timestamps. Users who prefer explicit
conflict resolution can select **Ask every time**.
## Verification
- `git diff --check`
- `platformio check --fail-on-defect low --fail-on-defect medium
--fail-on-defect high` — no defects
- `platformio run -e default` — firmware build successful
- The original implementation was manually smoke-tested on an X4 device.

## Summary
* **What is the goal of this PR?** Fixes#2402. On the X3, the "Time to
Sleep"
picker's 5-minute side buttons were inverted (left increased, right
decreased)
and the on-screen legend didn't match the physical buttons.
* **What changes are included?**
* Flip the large-step (±5 min) direction on X3 so the left side button
decreases and the right increases, matching the layout. X4 is unchanged.
* Add a device-specific step-hint string
(`STR_SLEEP_TIMER_STEP_HINT_X3`)
selected via `gpio.deviceIsX3()`. X3 shows `+/-: 1 min Side buttons: 5
min`;
X4 keeps the original `Left/Right: 1 min Up/Down: 5 min`.
* Same fix applied to both slider pickers that read the raw up/down side
buttons: the Time-to-Sleep picker and the "Go to %" picker
(`EpubReaderPercentSelectionActivity`), each with its own X3 hint string
(`STR_SLEEP_TIMER_STEP_HINT_X3`, `STR_PERCENT_STEP_HINT_X3`).
## Additional Context
* **Root cause:** the X3's side buttons sit one on each edge of the
screen
(power on top), whereas the X4 has a vertical up/down rocker on the
right
edge. So `BTN_UP` is physically the *left* button on X3 but the *top*
button
on X4. The picker mapped up→+5 / down→−5 unconditionally, which reads
naturally on the X4 rocker but inverted on the X3's left/right buttons.
The
static legend ("Up/Down: 5 min") had the same X3-only mismatch.
* The codebase already detects the device at runtime and handles this
layout
difference elsewhere (e.g. `LyraTheme::drawSideButtonHints` draws "Up on
left,
Down on right" for X3), so this reuses the same `gpio.deviceIsX3()`
signal.
* Swept the codebase for other side-button sliders:
`ClockOffsetActivity` already
uses the `Next/Previous` (`ButtonNavigator`) abstraction, which resolves
to
left=decrement / right=increment on X3, so it needs no change. List/page
navigation (Wi-Fi, KOReader sync, BMP viewer) and the keyboard cursor
are also
unaffected. The two slider pickers above were the only ones using raw
up/down.
* **X4 is untouched** — same direction, same legend wording as before.
* **Tested on X3 hardware:** left side button now decreases, right
increases, and
the legend matches. X4 not yet tested on device (no unit on hand); its
behaviour and strings are unchanged from master.
* **Translations:** the new `STR_SLEEP_TIMER_STEP_HINT_X3` and
`STR_PERCENT_STEP_HINT_X3` were added to all 26 languages, but the
non-English
ones are AI-generated and would benefit from a native-speaker pass —
particularly Hebrew (RTL ordering with a leading `+/-`), Kazakh, and
Vietnamese.

## Summary
* **What is the goal of this PR?**
* Fix the “Inverted” translation so reader orientation and color/filter
inversion can use separate labels.
* **What changes are included?**
* Adds `STR_ORIENTATION_INVERTED` for the inverted portrait orientation
option.
* Updates the reader orientation setting to use
`STR_ORIENTATION_INVERTED` instead of reusing `STR_INVERTED`.
* Leaves `STR_INVERTED` for the sleep cover filter and tilt page-turn
mode
* Adds the new orientation string across all 26 locale YAML files.
## Additional Context
* The original issue was found by a user in German, where `STR_INVERTED`
was translated as `Hochformat 180°`, which made sense for orientation
but not for color filters.
* This is a UI-label-only change. It does not change persisted
orientation values or settings behavior.
* Reviewer note: non-English wording may still benefit from
native-speaker review, especially for the new orientation-specific
labels and to verify the interchangeable usage between inverted color
and inverted tilt page turn direction.

## Summary
This PR enhances the EPUB reader's bookmark system with two
complementary improvements: a per-page bookmark indicator icon and
toggle behavior on the existing long-press action.
---
### What Changed
**Bookmark Toggle (was: add-only)**
The long-press Confirm action now toggles bookmarks rather than always
adding. `addBookmark()` checks whether a bookmark with the same xpath
already exists in the in-memory cache:
- If found → removes it and shows "Bookmark removed."
- If not found → adds it and shows "Bookmark added."
A new `STR_BOOKMARK_REMOVED` translation string was added to support the
removal message.
**Bookmark Icon Indicator**
A `BookmarkIcon` is now drawn at the top-right corner of the page
whenever the current page has a bookmark. `updateBookmarkFlag()` is
called at render time to determine whether the current page is
bookmarked.
**In-Memory Bookmark Cache**
Bookmarks are now loaded into `cachedBookmarks` on `onEnter()` rather
than being re-read from disk on every toggle. All subsequent add/remove
operations work against this cache and flush to disk, avoiding redundant
file reads on each bookmark action.
**Faster bookmarks list**
Previously, calculating "page X/Y" for each entry required decompressing
the entire spine item. We now persist `si`/`pc`/`pp` (spine index, page
count, and page progress) in the bookmark JSON when saving, and restore
them when loading. This avoids the expensive `toCrossPoint()` loop in
`onEnter()`, significantly reducing the cost of initializing the
bookmarks list.
---
### Files Changed
- `EpubReaderActivity.cpp` — `addBookmark()` toggle logic,
`updateBookmarkFlag()` (new), icon rendering in `renderContents()`,
cache initialization in `onEnter()`
- `EpubReaderActivity.h` — new fields: `currentPageBookmarked`,
`bookmarkRemoved`, `cachedBookmarks`; new method declaration
`updateBookmarkFlag()`

## Summary
* Adds a live font preview pane to the font selection screen so users
can see how a font looks before committing to it.
* Changes
* A preview pane occupying the top 30% of the font selection screen,
rendering sample pangram text in the previewed font
* A two-step confirm flow: first press (enter button) previews the font,
second press selects it
* Back restores the original font settings, so browsing has no side
effects
* Layout dimensions cached in `onEnter()` to avoid redundant
recalculation between `loop()` and `render()`
## Additional Context
* Preview sample text is hardcoded English; didn't want to use AI for
translation as I would not be able to verify the output in most
languages...
* The preview pane reduces visible list height; this is compensated by
passing the reserved height into `getNumberOfItemsPerPage`

## Summary
- Hold the menu (Confirm) button for ≥1s while reading an EPUB to launch
the existing `KOReaderSyncActivity` directly — replaces the three-step
path (open reader menu → scroll to Sync → confirm) with a single
gesture.
- Reuses `ReaderUtils::GO_HOME_MS` (same 1s threshold used by long-press
Back) and the existing `KOREADER_STORE.hasCredentials()` guard.
- Adds a Controls picker **"Long-press Menu"** (`longPressMenuFunction`,
default **Bookmark**) that **cycles through the available functions**
bound to the long-press gesture: `KOSync → Disabled → Bookmark`. The
field name and `LONG_PRESS_MENU_FUNCTION` enum are intentionally general
so future actions (dictionary lookup, table of contents, etc.) can be
appended without another schema migration. The setting is **not** a
binary toggle.
- Existing menu Sync entry still works — both call sites share one
extracted helper (`launchKOReaderSync`); no logic duplication.
- Short-press Confirm release is gated on duration so the reader menu
does not also open after a long press that *acts*, mirroring the
existing long-press Back pattern.
- **No-credentials fall-through:** `launchKOReaderSync()` now returns
whether it acted. When the function is set to KOSync but no KOReader
credentials are stored, the long-press is a no-op that **falls through
to open the reader menu** — so the menu stays reachable instead of the
hold silently swallowing the gesture. The release is only suppressed
when sync actually launched or surfaced a save error.
## Test plan
- [x] `pio run` succeeds clean for the `default` ESP32-C3 environment.
- [x] On-device, value **KOSync**, valid KOReader credentials:
long-press Confirm ≥1s → sync screen launches; get + update progress
return HTTP 200; release does **not** also open the reader menu; returns
to the same page.
- [x] On-device, value **KOSync**, **no** credentials: long-press
Confirm falls through and **opens the reader menu** (regression fix);
short-press also opens the menu.
- [x] On-device: menu → Sync still launches the same screen (shared
helper) and syncs (200/200).
- [x] On-device, value **Bookmark**: long-press drops a bookmark and
does **not** also open the menu.
- [x] On-device, value **Disabled**: long-press Confirm opens the menu
on release; no sync, no bookmark.
- [x] On-device: long-press Back still goes to the file browser
(unchanged path).
- [x] Heap: epub is released before the TLS handshake (frees ~16 KB);
min free heap stayed ~84 KB during sync, well above the safe floor. No
panics/OOM across the session.

## Summary
**What is the goal of this PR?**
Adds a clearer Quick Resume sleep-screen flow. The previous “Page as
Sleep Screen” behavior is now exposed as a dedicated `Sleep Screen >
Quick Resume `option, with the timeout-only behavior controlled by a
renamed `Quick Resume on Timeout `setting.
**What changes are included?**
- Adds `Quick Resume` as a new `Sleep Screen` option.
- Renames the old `Page as Sleep Screen` setting to `Quick Resume on
Timeout`.
- Changes that setting’s choices from `Never / After Timeout / Always`
to `OFF / ON`.
- Makes `Quick Resume on Timeout = ON` equivalent to the old `After
Timeout` behavior.
- Makes `Sleep Screen > Quick Resume` equivalent to the old `Always`
behavior.
- Automatically forces `Quick Resume on Timeout` to `ON` when `Sleep
Screen` is set to `Quick Resume`.
- Renames internal setting references from `seamlessSleepScreen` to
`quickResumeSleepScreen`.
- Updates translations for the renamed setting label.
**Additional Context**
- This is mostly a settings/labeling restructure around existing
behavior, not a new rendering path.
- The runtime quick-resume behavior still uses the existing saved
framebuffer / last-screen sleep flow.
- Review focus areas:
- Sleep entry behavior from manual sleep vs timeout sleep.
- The automatic dependency where selecting `Sleep Screen > Quick Resume`
sets `Quick Resume on Timeout` to `ON`.

New option: `Page as Sleep Screen` - `Never (default)`, `After Timeout`,
`Always`
When enabled, it seamlessly sleeps on timeout or power off, making a
fast refresh for the moon icon. When waking up, we still show the last
page, instead of the boot screen, making it fully seamless.
I tried different icons such as "refresh arrow" and others, but they
looked not as nice as 3 simple dots.
With this mode, the device turns off 4 seconds faster. And has 6 seconds
less delay when turning back on. Much more responsive.
Previously, even a 10-minute timeout sometimes wasn't enough, and I'd
worry about seeing the book cover. It's now easier to use a shorter
sleep timeout: if I get distracted during a reading session but don't
want to stop, the new screen is much more inviting to come back to.

## Summary
This PR introduces **Focus Reading**, a generic implementation of
artificial fixation points (similar to Bionic Reading) designed to
improve reading speed and focus by bolding the initial characters of
words. This is achieved by dynamically bolding characters during
indexing.
<img width="500" alt="Focus Reading on X3"
src="https://github.com/user-attachments/assets/94a632a5-82da-47be-957c-538b35bf84d9"
/>
### Implementation Details
#### Core Text Engine (`ParsedText`)
- Modified `ParsedText::addWord` to implement a custom bolding
algorithm. It uses a 45% ratio for bolding, with a minimum of 1
character and a maximum of 9.
- UTF-8 Safety: Integrated `utf8NextCodepoint` to ensure character
counting and string slicing occur at safe byte boundaries, preventing
corruption of multi-byte characters (e.g., accented letters or smart
quotes).
- Intelligent Tokenization: This correctly identifies and separates
"word" characters (letters, apostrophes, hyphens) from "non-word"
characters (numbers, brackets, smart quotes).
- Formatting Preservation: The logic ensures that punctuation is not
"stolen" for the bolding count and that existing styles (like italics or
underlines) are preserved across the bold/regular split.
- Processing at indexing stage reduces CPU load at render-time and
ensures layout/fit is unaffected.
- Split details are tracked with `wordIsFocusSuffix`. After splitting
and layout, suffixes are merged back into their preceding word entries
to prevent a doubling of RAM usage.
#### Settings and UI
- Version Management: Bumped `SECTION_FILE_VERSION` to `21`
- Global Settings: Added `focusReadingEnabled` to `CrossPointSettings`.
- User Interface: Added a new toggle in the "Reader" section of the
settings menu, positioned after the "Embedded Style" option.
- Localization: Added the `STR_FOCUS_READING` string
#### Plumbing
- Plumbed the `focusReadingEnabled` boolean through
`EpubReaderActivity`, `Section`, and `ChapterHtmlSlimParser` to ensure
the user's setting reaches the `ParsedText` constructor during chapter
indexing.
## Additional Context
### Files Changed
- `lib/Epub/Epub/ParsedText.h / .cpp`: Core fixation logic and UTF-8
tokenization.
- `lib/Epub/Epub/Section.h / .cpp`: Cache header updates and
invalidation logic.
- `lib/Epub/Epub/parsers/ChapterHtmlSlimParser.h / .cpp`: Plumbing the
setting to text blocks.
- `src/CrossPointSettings.h`: Data persistence for the new setting.

## Summary
* **What is the goal of this PR?** Fix KOSync failing with "Network
error" on large/complex EPUBs, and simplify the sync navigation flow by
removing the callback/result pattern.
* **What changes are included?**
This PR combines the approaches from #1855 and #1760 into a single,
cleaner solution:
**Memory fix (from #1855):**
- `EpubReaderActivity` pre-computes the local KOReader position and
chapter name, then explicitly releases `epub` and `section` before
launching `KOReaderSyncActivity`. This frees ~65KB measured on device,
giving the TLS handshake sufficient heap. The root cause was
`MBEDTLS_ERR_X509_ALLOC_FAILED` (-0x2880) when a 3-cert chain consumed
~48KB during the handshake with only ~50KB available.
- `KOReaderSyncActivity` no longer receives a `shared_ptr<Epub>` at
construction — it lazy-loads the Epub after TLS only if remote progress
is found (`ensureEpubLoaded()`).
- Added `MIN_HEAP_FOR_TLS = 55000` guard in `KOReaderSyncClient` —
returns `LOW_MEMORY` early if aggregate free heap is too low before
attempting a TLS connection.
**Navigation simplification (from #1760):**
- Replaced `startActivityForResult` + callback with
`activityManager.replaceActivity` / `activityManager.goToReader`.
Progress is saved to `progress.bin` before the epub is released
(cancel/upload paths) and in `saveProgressAndReturn` (apply remote
path). The reader re-launches from the saved position naturally via
`goToReader`, eliminating the need to reload the epub in a callback.
- Extracted `ReaderUtils::saveProgress()` as a shared helper used by
both `EpubReaderActivity` and `KOReaderSyncActivity`.
- Added `STR_SAVE_PROGRESS_FAILED` to all 22 language files for the case
where writing the synced position to SD fails.
**Orientation fix (found during device testing):**
- `EpubReaderActivity::onExit()` resets the renderer to portrait before
destruction. With `replaceActivity` the reader is fully torn down before
KOSync starts, so KOSync was always rendering in portrait even when
reading in landscape. Fixed by calling `ReaderUtils::applyOrientation`
in `KOReaderSyncActivity::onEnter()`.
## Additional Context
Heap measurements on device (large EPUB with complex CSS):
| Metric | Before | After |
|---|---|---|
| Heap before Epub release | 88,156 bytes | — |
| Heap after Epub release | — | 153,892 bytes (+65,736) |
| Heap at TLS handshake | ~50,000 bytes (fails) | ~116,384 bytes
(passes) |
| Min-free-ever during sync session | 2,600 bytes | 33,052 bytes |
| TLS result | `MBEDTLS_ERR_X509_ALLOC_FAILED` | HTTP 200 |
Tested on device: sync from inside a large EPUB in both portrait and
landscape, cancel, apply remote progress, upload local progress.

Add a complete SD card font subsystem that enables users to install and
use custom fonts beyond the three built-in families. This combines the
back-end firmware support (#1327) with the font configuration, build
pipeline, CI distribution, and user-facing management UI (#1392).
Core font system:
- Custom .cpfont binary format (v4) with multi-style support (regular,
bold, italic, bold-italic) packed into a single file per size
- On-demand glyph loading from SD card with two-pass prewarm rendering
to bulk-read glyphs per page, achieving near-flash performance for
Latin text (~697ms vs ~681ms) and viable CJK rendering (~32% slower)
- Persistent advance cache for layout measurement without SD I/O
- Overflow ring buffer for glyph cache misses during rendering
- Memory-conscious design: only advance tables kept in RAM; glyph
bitmaps, kern tables, and ligatures loaded on demand from SD
Font management:
- On-device WiFi download from GitHub Releases with manifest-based
discovery, install/update detection, and progress UI
- Web interface font upload, listing, and deletion via /fonts page
- Manual SD card copy to /fonts/ or /.fonts/ directories
- Font selection integrated into Settings > Reader > Font Family
Build pipeline:
- Declarative YAML config (sd-fonts.yaml) as single source of truth
for the 17-family font library (serif, sans, mono, accessibility)
- Python converter (fontconvert_sdcard.py) for TTF/OTF to .cpfont with
FreeType rasterization, class-based kerning, and ligature extraction
- Parallel build orchestrator with variable font instance extraction
- CI workflow publishing versioned + stable releases to a dedicated
crosspoint-fonts repository with auto-incrementing revision tags
- Centralized version constants (cpfont_version.py) shared across
build tooling and CI, with firmware headers as manual sync points
Additional fixes:
- CJK characters no longer get hyphens inserted at line breaks
- Advance table eliminates 30+ second stalls during CJK section
indexing for paragraphs with >512 unique codepoints
Closes#930

## Summary
Add ability to show a status bar for 1-bit XTC files (closes#1848)
Overlays a status bar (similar style to that for epubs) over the image.
Defaults to hidden, users can set to show and either top or bottom of
the screen within "Customize Status Bar" reader settings.
I've leaned toward a simple overlay approach rather than trying anything
clever e.g. resizing the original image or allowing for shifting the
image around. I think it's more straight forward for the user to create
a buffer zone when generating the XTC files.
For 2-bit image files, it'd require more work to handle the multiple
render passes so I'm holding off on that.

## 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.

## 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.

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

## Summary
If the system reboots from crash, display the reason and tell user to
include `crash_report.txt` file.
To test this, simply add an `assert(false)` somewhere inside the code.
