* Add "Keep Screen On" feature to PDF and Epub readers.
* Add `rawLibraryFiles` to `MainViewModel` and improve file path resolution in `SharedComposables`.
Specifically:
- Updated `MainViewModel` state and UI logic to track and provide unfiltered library files.
- Enhanced file path formatting in `SharedComposables` to better handle Document, Tree, and primary storage URIs.
- Added scrollable support for long text values in `DetailItem` composable.
- Passed `rawLibraryFiles` to `FolderSyncScreen` to ensure sync logic uses the base file list.
* Update info bar background and text colors in EpubReaderScreen to match the selected theme.
* Prevent accidental UI bar toggles immediately after scrolling in EPUB vertical mode.
* feat: implement EPUB highlights sync and legacy migration
- Implement Cloud and Local Folder sync for EPUB highlights.
- Add highlight JSON serialization/deserialization helpers in EpubReaderAnnotations.
- Implement automatic migration of highlights from SharedPreferences to the Database on book open.
- Add cleanup logic to remove legacy SharedPreferences data after successful DB migration.
- Update RecentFilesRepository to trigger local folder metadata sync when highlights are modified.
- Update FolderSyncWorker to pull highlights and custom names from linked folder metadata.
* Update intent filters
* Added support for filtering file types in synced folders
* Added support for custom file names and enhanced file information dialog
* added feedback option in the homescreen drawer
* Implemented a limit for number of recent files displayed on the home screen
* Implemented PDF reflow mode by introducing a mechanism to convert PDF content to Markdown/HTML for viewing in the EPUB reader.
Specific changes include:
- Added `PdfReflowGenerator` and `PdfToMarkdownGenerator` to handle PDF text extraction and conversion to reflowable formats.
- Updated `MainViewModel` with `toggleReflowMode` logic to switch between original PDF and reflowed views.
- Modified `RecentFileEntity` and `RecentFileDao` to persist user reflow preferences, including a Room database migration (v12 to v13).
- Updated `PdfViewerScreen` and `EpubReaderControls` to include UI options for toggling reflow mode.
- Integrated reflow preference check into the book opening workflow to automatically load the preferred view.
- Updated `AppNavigation` and `EpubReaderScreen` to support the new view switching state.
* Implemented background processing and incremental loading for PDF reflow mode.
- Added `reflowProgress` to `MainViewModel` to track and display PDF-to-Markdown conversion progress in the UI.
- Refactored `PdfToMarkdownGenerator` to generate a skeleton EPUB structure immediately while processing page content (text and images) asynchronously.
- Switched PDF text extraction to use `PDFBox` with optimized memory settings and JPEG compression for images.
- Implemented priority page processing in reflow mode, starting with the user's current page.
- Added "Clear Reflow Cache" debug option to the Home Screen.
- Enhanced `BookPaginator` to support lazy loading of chapter content from disk and improved cache hit detection.
* Refactored PDF Reflow Mode to generate standalone Markdown files instead of temporary EPUB books.
* perf(reflow): optimize PDF-to-Markdown conversion and fix viewing lag
- Re-architected PdfToMarkdownGenerator to use a single-pass stream (O(N) complexity), fixing performance bottlenecks and timeouts on large PDFs.
- Implemented "Virtual Chaptering" in SingleFileImporter for Markdown files to split content into page-level HTML files, eliminating UI lag during reading.
- Simplified ReflowWorker to delegate progress tracking and looping to the generator.
- Enhanced PdfViewerScreen with a prominent top-bar progress indicator and a completion snackbar with an "OPEN" action.
* Optimized EPUB parsing performance and fixed PDF viewer UI layout.
- Optimized `EpubParser` by implementing parallel chapter parsing using coroutines and a semaphore to limit concurrency.
- Reduced memory usage in `EpubParser` and `SingleFileImporter` by no longer storing full HTML content in memory for chapters.
- Updated `EpubXMLFileParser` to support an existing `Document` object to avoid redundant Jsoup parsing.
- Fixed an issue in `PdfViewerScreen` where the snackbar was appearing under the bottom app bar.
docs: Revamp README and add APK naming convention
This commit introduces a complete overhaul of the `README.md` to improve project presentation. Key changes include:
* Adds a new header with the app icon and a Google Play badge.
* Updates the feature graphic and includes a note distinguishing the OSS version from the Play Store version.
* Refines the "Open Source Libraries" section to be more structured.
* Moves the main preview image into the `docs` directory.
Additionally, the `app/build.gradle.kts` file is updated to configure a standardized naming convention for output APK files, including flavor, version, and build type.
* refactor copyright headers and fix README icon alignment
This commit introduces two main changes across the codebase:
The `spotless/copyright.kt` template have been updated for consistency:
* The author name is simplified from "Episteme Authors" to "Episteme".
* The contact email prefix is shortened from "Electronic mail:" to "mail:".
Second, the `README.md` file is adjusted to correct the vertical alignment of the app icon with the project title.
