Quick Menu UI Improvements:
- Add navigation button hints (prev/next on front buttons, up/down on side buttons)
- Fix orientation-aware margins for button hint areas in landscape modes
Screen Rotation Toggle:
- Add "Rotate Screen" option to toggle between Portrait and Landscape CCW
- Force section reindex when orientation changes to properly reflow content
- Position is automatically restored via content offset after reindex
Customizable Menu Order:
- Add "Edit List Order" option (fixed at bottom of menu)
- Pick-and-place reordering: select item to move, navigate to destination, place
- Visual feedback: filled highlight for cursor, outlined box for item being moved
- Menu order persists in settings (quickMenuOrder array in CrossPointSettings)
- New default order: Bookmark, Dictionary, Rotate Screen, Settings, Clear Cache
Files changed:
- CrossPointSettings.h: Add quickMenuOrder[5] setting
- QuickMenuActivity.h/cpp: Edit mode, order rendering, pick-and-place logic
- EpubReaderActivity.cpp: Handle TOGGLE_ORIENTATION action with section reset
Fixes device hanging when booted without USB connected. The root cause
was calling Serial.available() and Serial.read() in checkForFlashCommand()
when Serial.begin() was never called (USB not connected at boot).
Changes:
- Add if (!Serial) return guard to checkForFlashCommand()
- Restore upstream while (!Serial) wait loop with 3s timeout
- Remove Serial.setTxTimeoutMs(0) (not in upstream, may cause issues)
- Remove unnecessary if (Serial) guards from EpubReaderActivity.cpp
(Serial.printf is safe without guards, only input calls need them)
Key insight: Serial.printf() is safe without guards (returns 0 when not
initialized), but Serial.available()/Serial.read() cause undefined
behavior on ESP32-C3 USB CDC when called without Serial.begin().
See: claude_notes/usb-serial-blocking-fix-2026-01-28.md
On ESP32-C3 with USB CDC, Serial.printf() blocks indefinitely when USB
is not connected. This caused device freezes when booted without USB.
Solution: Call Serial.setTxTimeoutMs(0) after Serial.begin() to make
all Serial output non-blocking.
Also added if (Serial) guards to high-traffic logging paths in
EpubReaderActivity as belt-and-suspenders protection.
Includes documentation of the debugging process and Serial call inventory.
Also applies clang-format to fix pre-existing formatting issues.
Move cachedRenderer, cachedMappedInput, and cachedSection declarations
into the DICTIONARY action block where they're actually used, addressing
cppcheck variableScope warnings.
- Fix ignored return value in TxtReaderActivity
- Remove unused variables across multiple files
- Add const correctness to DictionaryMargins and EpubReaderActivity
- Replace inefficient substr patterns with resize+append
- Use STL algorithms (find_if, any_of, copy_if, transform) where applicable
- Remove dead sync placeholder code in EpubReaderChapterSelectionActivity
- Add cppcheck suppression for ValueFlow analysis limitation
Resolves all low, medium, and high severity cppcheck defects.
Merges progress bar status bar feature from merge-438:
- Added FULL_WITH_PROGRESS_BAR and ONLY_PROGRESS_BAR status bar modes
- Added drawBookProgressBar() to ScreenComponents
Preserves features from current branch:
- Content offset tracking for position restoration (EPUB_PROGRESS_VERSION)
- drawBatteryLarge() function
- Sleep Screen Cover Mode "Actual" option
Integrates upstream PR #511 changes while preserving local delete/archive
functionality. Key changes:
- Add RecentBook struct with path, title, author fields
- Update RecentBooksStore to store and serialize metadata
- Implement version migration for existing recent.bin files
- Update MyLibraryActivity to display two-line items (title + author)
- Update EpubReaderActivity and XtcReaderActivity to pass metadata
Maintains backwards compatibility with delete/archive feature from
local commit d5a9873.
## Summary
Give space to the chapter title if we don't show battery percentage.

# Summary
This PR introduces a reusable Tab Bar component and combines the Recent
Books and File Browser into a unified tabbed page called "My Library"
accessible from the Home screen.
## Features
### New Tab Bar Component
A flexible, reusable tab bar component added to `ScreenComponents` that
can be used throughout the application.
### New Scroll Indicator Component
A page position indicator for lists that span multiple pages.
**Features:**
- Up/down arrow indicators
- Current page fraction display (e.g., "1/3")
- Only renders when content spans multiple pages
### My Library Activity
A new unified view combining Recent Books and File Browser into a single
tabbed page.
**Tabs:**
- **Recent** - Shows recently opened books
- **Files** - Browse SD card directory structure
**Navigation:**
- Up/Down or Left/Right: Navigate through list items
- Left/Right (when first item selected): Switch between tabs
- Confirm: Open selected book or enter directory
- Back: Go up directory (Files tab) or return home
- Long press Back: Jump to root directory (Files tab)
**UI Elements:**
- Tab bar with selection indicator
- Scroll/page indicator on right side
- Side button hints (up/down arrows)
- Dynamic bottom button labels ("BACK" in subdirectories, "HOME" at
root)
## Tab Bar Usage
The tab bar component is designed to be reusable across different
activities. Here's how to use it:
### Basic Example
```cpp
#include "ScreenComponents.h"
void MyActivity::render() const {
renderer.clearScreen();
// Define tabs with labels and selection state
std::vector<TabInfo> tabs = {
{"Tab One", currentTab == 0}, // Selected when currentTab is 0
{"Tab Two", currentTab == 1}, // Selected when currentTab is 1
{"Tab Three", currentTab == 2} // Selected when currentTab is 2
};
// Draw tab bar at Y position 15, returns height of the tab bar
int tabBarHeight = ScreenComponents::drawTabBar(renderer, 15, tabs);
// Position your content below the tab bar
int contentStartY = 15 + tabBarHeight + 10; // Add some padding
// Draw content based on selected tab
if (currentTab == 0) {
renderTabOneContent(contentStartY);
} else if (currentTab == 1) {
renderTabTwoContent(contentStartY);
} else {
renderTabThreeContent(contentStartY);
}
renderer.displayBuffer();
}
```

- Implements a fix to truncate chapter names that exceeds display width
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).
- Prior to the fix, if the book contains multiple chapters with names
longer than the display width, there is a noticeable delay when
scrolling through the list of chapters.

## Summary
* Adds (optional) Hyphenation for English, French, German, Russian
languages
## Additional Context
* Included hyphenation dictionaries add approximately 280kb to the flash
usage (German alone takes 200kb)
* Trie encoded dictionaries are adopted from hypher project
(https://github.com/typst/hypher)
* Soft hyphens (and other explicit hyphens) take precedence over
dict-based hyphenation. Overall, the hyphenation rules are quite
aggressive, as I believe it makes more sense on our smaller screen.

## Summary
* This builds upon the helpful PR
https://github.com/crosspoint-reader/crosspoint-reader/pull/341, and
adds support for the setting to also apply to the XTC reader, which I
believed has just been missed and was not intentionally left out.
* XTC does not have chapter support yet, but it does skip 10 pages when
long-pressed, and so I think this is useful.

### AI Usage
Did you use AI tools to help write this code? No
## Summary
Adds a new "Long-press Chapter Skip" toggle in Settings to control
whether holding the side buttons skips chapters.
I kept accidentally triggering chapter skips while reading, which caused
me to lose my place in the middle of long chapters.
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).

## Summary
* **What is the goal of this PR?**
Add support for reading plain text (.txt) files, enabling users to
browse, read, and track progress in TXT documents alongside existing
EPUB and XTC formats.
* **What changes are included?**
- New Txt library for loading and parsing plain text files
- New TxtReaderActivity with streaming page rendering using 8KB chunks
to handle large files without memory issues on ESP32-C3
- Page index caching system (index.bin) for instant re-open after sleep
or app restart
- Progress bar UI during initial file indexing (matching EPUB style)
- Word wrapping with proper UTF-8 support
- Cover image support for TXT files:
- Primary: image with same filename as TXT (e.g., book.jpg for book.txt)
- Fallback: cover.bmp/jpg/jpeg in the same folder
- JPG to BMP conversion using existing converter
- Sleep screen cover mode now works with TXT files
- File browser now shows .txt files
## Additional Context
* Add any other information that might be helpful for the reviewer
* Memory constraints: The streaming approach was necessary because
ESP32-C3 only has 320KB RAM. A 700KB TXT file cannot be loaded entirely
into memory, so we read 8KB chunks and build a page offset index
instead.
* Cache invalidation: The page index cache automatically invalidates
when file size, viewport width, or lines per page changes (e.g., font
size or orientation change).
* Performance: First open requires indexing (with progress bar),
subsequent opens load from cache instantly.
* Cover image format: PNG is detected but not supported for conversion
(no PNG decoder available). Only BMP and JPG/JPEG work.
## Summary
* **What is the goal of this PR?**
* This PR adds a setting to (additionally) map the forward page turn
onto the powerbutton when in `EPUBReaderActivity` and powerbutton short
press is not mapped to sleep mode. I find the powerbutton to be exactly
where my thumb is while reading so it is very convenient to map the
forwardpage turn to that. Maybe Im not alone with this ^^
* **What changes are included?**
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks, specific areas to
focus on).
## Summary
Fixes https://github.com/daveallie/crosspoint-reader/issues/233
## Additional Context
By disabling the Text Anti-Aliasing in the settings, you can get faster
black-and-white page turns that work exactly like the stock firmware,
instead of having an additional flash after rendering (see issue linked
above for example).
Tested on the X4 and confirmed working.

## Summary
Adds feature to file selection activity for better user navigation when
ascending folders. The activity now remembers the index of the parent
folder instead of always resetting to the first element.
I don't have any means of testing this, so if someone could test it
that'd be great
Resolves#259
## Summary
* **What is the goal of this PR?**
* This PR adds a setting to control the top left and right margins of
the reader screen in 4 sizes (5, 10, 20, 40 pt?) and defaults to `SMALL`
which is equivalent to the fixed margin of 5 that was already in use
before.
* **What changes are included?**
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks, specific areas to
focus on).

## Summary
* **What is the goal of this PR?**
Add a new user setting for paragraph alignment, instead of hard-coding
full justification.
* **What changes are included?**
One new line in the settings screen, with 4 options
(justify/left/center/right). Default is justified since that's what it
was already. I personally only wanted to disable justification and use
"left", but I included the other options for completeness since they
were already supported.
## Additional Context
Tested on my X4 and looks as expected for each alignment.
