Vincent Politzer 4e5e2fe40a feat: focus reading (#1670)
## 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.
- `src/SettingsList.h`: UI toggle implementation.

Wylan SwetsandClaude Sonnet 4.6 e64155ed63 fix: free Epub RAM and simplify KOSync navigation via ActivityManager (#1860)
## 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.

7993b2bb97 feat: add SD card font support with on-device download and web management
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

Chun Ming LeeandZach Nelson 29fd29f537 feat: Status bar for XTC files (#1849)
## 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.

Sample from a Japanese text XTC

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.

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

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

file uploading.)

Allow users to better manage their epub library by offloading unwanted
or finished books and other files. Resolves #893

* **What changes are included?**

Added Delete Book shortcut in the fil browser. Delete function
implements the new ConfirmationActivity to show file name and solicit
user interaction before either returning to the file browser on a press
of the back button, or proceeding to delete. Delete function then
deletes the file and returns user to the file browser menu at the
current directory. Video of it working on my machine attached here:

## Additional Context

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

Certainly potential risks associated with file deletion. Please let me
know if there are any concerns that need to be better addressed. I think
this is a very good feature to have to go along with the new screenshots
so you don't get stuck with a bunch of extra files on your device. Also
I did add this to the user guide.

09cef70709 fix: clarity issue with ambiguous string SET (#1169)
## Summary

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

Fixes a clarity issue regarding the translation string `STR_SET`. The
issue lies in the fact that the english word can have different
meanings.

The only time the string is used is in the language selectio screen,
where it has the meaning of _selected_. (As in _The language has been
**set** to French_).

Another meaning can be _configured_. (As in _The KOReader username has
been __set__). This is the meaning many of the translations have taken.
The reason that the string is right above `STR_NOT_SET` (which is meant
as _not configured_).

With this PR I propose to explicitly use the term "_Selected_". There
are two good reasons for this:
+ it removes the confusion and the misleading translations
+ it is consistent with the button label `Select`, communicating the
link between the two (the row will be marked `Selected` if you press the
buttpn `Select`. Much clearer than now)

* **What changes are included?**

Removed the unused strings and added translations for the new string
`STR_SELECTED` for the languages I know.

the Issue was introduced in #1020. Previously, if a language was
selected it was marked with `[ON]` (`STR_ON_MARKER`). I considered
reverting it back to that, but the solution I described above seemed
superior.

Uri TauberandArthur Tazhitdinov 30d8a8d011 feat: slim footnotes support (#1031)
## Summary
**What is the goal of this PR?** Implement support for footnotes in epub
files.
It is based on #553, but simplified — removed the parts which
complicated the code and burden the CPU/RAM. This version supports basic
footnotes and lets the user jump from location to location inside the
epub.

**What changes are included?**
- `FootnoteEntry` struct — A small POD struct (number[24], href[64])
shared between parser, page storage, and UI.
- Parser: `<a href>` detection (`ChapterHtmlSlimParser`) — During a
single parsing pass, internal epub links are detected and collected as
footnotes. The link text is underlined to hint navigability.
Bracket/whitespace normalization is applied to the display label (e.g.
[1] → 1).
- Footnote-to-page assignment (`ChapterHtmlSlimParser`, `Page`) —
Footnotes are attached to the exact page where their anchor word
appears, tracked via a cumulative word counter during layout, surviving
paragraph splits and the 750-word mid-paragraph safety flush.
- Page serialization (`Page`, `Section`) — Footnotes are
serialized/deserialized per page (max 16 per page). Section cache
version bumped to 14 to force a clean rebuild.
- Href → spine resolution (`Epub`) — `resolveHrefToSpineIndex()` maps an
href (e.g. `chapter2.xhtml#note1`) to its spine index by filename
matching.
- Footnotes menu + activity (`EpubReaderMenuActivity`,
`EpubReaderFootnotesActivity`) — A new "Footnotes" entry in the reader
menu lists all footnote links found on the current page. The user
scrolls and selects to navigate.
- Navigate & restore (`EpubReaderActivity`) — `navigateToHref()` saves
the current spine index and page number, then jumps to the target. The
Back button restores the saved position when the user is done reading
the footnote.

  **Additional Context**

**What was removed vs #553:** virtual spine items
(`addVirtualSpineItem`, `isVirtualSpineItem`), two-pass parsing,
`<aside>` content extraction to temp HTML files, `<p class="note">`
paragraph note extraction, `replaceHtmlEntities` (master already has
`lookupHtmlEntity`), `footnotePages` / `buildFilteredChapterList`,
`noterefCallback` / `Noteref` struct, and the stack size increase from 8
KB to 24 KB (not needed without two-pass parsing and virtual file I/O on
the render task).
 
**Performance:** Single-pass parsing. No new heap allocations in the hot
path — footnote text is collected into fixed stack buffers (char[24],
char[64]). Active runtime memory is ~2.8 KB worst-case (one page × 16
footnotes × 88 bytes, mirrored in `currentPageFootnotes`). Flash usage
is unchanged at 97.4%; RAM stays at 31%.
   
**Known limitations:** When clicking a footnote, it jumps to the start
of the HTML file instead of the specific anchor. This could be
problematic for books that don't have separate files for each footnote.
(no element-id-to-page mapping yet - will be another PR soon).

ariel-lindemann 7e214ea760 feat: sort languages in selection menu (#1071)
## Summary

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

Currently we are displaying the languages in the order they were added
(as in the `Language` enum). However, as new languages are coming in,
this will quickly be confusing to the users.

But we can't just change the ordering of the enum if we want to respect
bakwards compatibility.

So my proposal is to add a mapping of the alphabetical order of the
languages. I've made it so that it's generated by the `gen_i18n.py`
script, which will be used when a new language is added.


* **What changes are included?**

Added the array from the python script and changed
`LanguageSelectActivity` to use the indices from there. Also commited
the generated `I18nKeys.h`

## 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 was wondering if there is a better way to sort it. Currently, it's by
unicode value and Czech and Russian are last, which I don't know it it's
the most intuitive.

The current order is:
`Català, Deutsch, English, Español, Français, Português (Brasil),
Română, Svenska, Čeština, Русский`

James WhyteandArthur Tazhitdinov 2d49c7b7b4 feat: split status bar setting (#733)
## Summary

This PR aims to reduce the complexity of the status bar by splitting the
setting into 5:
- Chapter Page Count
- Book Progress %
- Progress Bar
- Chapter Title
- Battery Indicator

These are located within the new StausBarSettings activity, which also
shows a preview of the bar the user has created

<img width="513" height="806" alt="image"
src="https://github.com/user-attachments/assets/cdf852fb-15d8-4da2-a74f-fd69294d7b05"

src="https://github.com/user-attachments/assets/66fc0c0d-ee51-4d31-b70d-e2bc043205d1"
/>


When updating from a previous version, the user's past settings are
honoured.

## Additional Context

The PR aims to remove any duplication of status bar code where possible,
and extracts the status bar rendering into a new component - StatusBar

It also adds a new (optional) padding option to the progress bar to
allow the status bar to be shifted upwards - this is only intended for
use in the settings.

Bram Schulting f16c0e52fd feat: Tweak Lyra popup UI (#768)
## Summary

I want to preface this PR by stating that the proposed changes are
subjective to people's opinions. The following is just my suggestion,
but I'm of course open to changes.

The popups in the currently implemented version of the Lyra theme feel a
bit out of place. This PR suggests an updated version which looks a bit
more polished and in line with the rest of the theme.

I've also taken the liberty to remove the ellipsis behind the text of
the popups, as they made the popup feel a bit off balance (example
below).

With the applied changes, popups will look like this.


![IMG_0012](https://github.com/user-attachments/assets/a954de12-97b8-4102-be17-a702c0fe7d1e)

The vertical position is (more or less) aligned to be in line with the
sleep button. I'm aware the popup is used for other purposes aside from
the sleep message, but this still felt like a good place. It's also a
place where your eyes naturally 'rest'.

The popup has a small 2px white outline, neatly separating it from
whatever is behind it.

### Alternatives considered and rationale behind proposal

Initially I started out worked off the Figma design for the Lyra theme,
which [moves the
popups](https://www.figma.com/design/UhxoV4DgUnfrDQgMPPTXog/Lyra-Theme?node-id=2011-19296&t=Ppj6B2MrFRfUo9YX-1)
to the bottom of the screen. To me, this results in popups that are much
too easy to miss:


![IMG_0006](https://github.com/user-attachments/assets/b8ce3632-94a9-494e-8256-d87a6ee60cdf)

After this, I tried moving the popup back up (to the position of the
sleep button), but to me it still kinda disappeared into the text of the
book:


![IMG_0008](https://github.com/user-attachments/assets/4b05df7c-932e-432b-9c10-130da3109050)

Inverting the colors of the popup made things stand out the perfect
amount in my opinion. The white outline separates the popup from what is
behind it.


![IMG_0011](https://github.com/user-attachments/assets/77b1e8cc-0a57-4f4b-9abb-a9d10988d919)

This looked much better to me. The only thing that felt a bit off to me,
was the balance due to the ellipsis at the end of the popup text. Also,
"Entering Sleep..." felt a bit.. engineer-y. I felt something a bit more
'conversational' makes at all feel a bit more human-centric. But I'm no
copywriter, and English is not even my native language. So feel free to
chip in!

After tweaking that, I ended up with the final result:

_(Same picture as the first one shown in this PR)_

7ba5978848 feat: User-Interface I18n System (#728)
## Summary

**What is the goal of this PR?**
This PR introduces Internationalization (i18n) support, enabling users
to switch the UI language dynamically.

**What changes are included?**
- Core Logic: Added I18n class (`lib/I18n/I18n.h/cpp`) to manage
language state and string retrieval.

- Data Structures:

- `lib/I18n/I18nStrings.h/cpp`: Static string arrays for each supported
language.
  - `lib/I18n/I18nKeys.h`: Enum definitions for type-safe string access.
  - `lib/I18n/translations.csv`: single source of truth. 

- Documentation: Added `docs/i18n.md` detailing the workflow for
developers and translators.

- New Settings activity:
`src/activities/settings/LanguageSelectActivity.h/cpp`

## Additional Context

This implementation (building on concepts from #505) prioritizes
performance and memory efficiency.

The core approach is to store all localized strings for each language in
dedicated arrays and access them via enums. This provides O(1) access
with zero runtime overhead, and avoids the heap allocations, hashing,
and collision handling required by `std::map` or `std::unordered_map`.

The main trade-off is that enums and string arrays must remain perfectly
synchronized—any mismatch would result in incorrect strings being
displayed in the UI.

To eliminate this risk, I added a Python script that automatically
generates `I18nStrings.h/.cpp` and `I18nKeys.h` from a CSV file, which
will serve as the single source of truth for all translations. The full
design and workflow are documented in `docs/i18n.md`.

### Next Steps

- [x] Python script `generate_i18n.py` to auto-generate C++ files from
CSV
- [x] Populate translations.csv with initial translations.

Currently available translations: English, Español, Français, Deutsch,
Čeština, Português (Brasil), Русский, Svenska.
Thanks, community!

**Status:** EDIT: ready to be merged.

As a proof of concept, the SPANISH strings currently mirror the English
ones, but are fully uppercased.
