* Fixed: Open library button not working.
* Fixed: opening ZIM file from storage (using the plus button) had too much bottom margin after migrating MainActivity to Compose.
* Added support for automatically hiding and showing the BottomAppBar while scrolling, using the Compose approach.
* Many other improvements in UI and logics.
* Show or hide the BottomAppBar when full screen mode is enabled/disabled or when tabs are visible.
* Disable the left drawer when opening full screen mode, tabs, etc.
* Removed the `DefaultLanguageProvider` since now it is unused according to this new approach.
* Refactored the `SaveLanguagesAndFinishTest` unit test according to this new approach.
* Improved the UI to show the selected language on `OnlineLibrary` screen to inform users which language they have selected for fetching the ZIM files.
* Refactored the code to apply the search filter same like kiwix server.
* Previously, we used `Locale.getISOLanguages()` to display the language list. However, this did not include all the languages in which books are available. Now, we use the `OPDS` stream via libkiwix to fetch online books, and utilize a method in libkiwix that provides the list of available book languages. This dynamically retrieved list is now shown in the `LanguageFragment`, allowing users to select a language and download books accordingly.
* The `LanguageFragment` previously relied on `ObjectBox` for storing and managing selected languages. This has now been migrated to use `Room` database instead.
* A migration strategy has been added to move previously selected languages from ObjectBox to Room.
* Corresponding test cases for migration have been added, and existing tests have been refactored to reflect these changes.
* Since we now rely on `libkiwix` to retrieve the language list, the `ZimManageViewModelTest` initially failed due to native code dependencies (JNI) not loading in unit test environments. To address this, we refactored the code and introduced a `JNIModule` class in the app module (where `OnlineLibraryManager` resides). We now inject the `Library` object, allowing us to pass a mocked instance to `ZimManageViewModel` for proper unit testing.
* Implemented the `DonationLayout` using Compose UI.
* Refactored the `ReaderScreen` to integrate the new Compose-based layout.
* Added a maximum width constraint to the donation layout to prevent it from appearing too wide in landscape mode or on tablets.
* Removed unused code from the project.
* Moved the scrolling logic of the WebView into the Compose UI, as custom scroll handling in the WebView was causing issues.
* Removed ToolbarScrollingKiwixWebView since it's no longer needed—scrolling is now managed entirely within Compose.
* Added animations for opening and closing the tab switcher view.
* Fixed: Missing bottom margin in custom apps.
* Fixed: Reader's bottom app bar not appearing after closing or selecting a tab.
* Fixed: Menu not showing in the toolbar when the application is freshly launched in custom apps.
* Refactored the scroll behavior of the toolbar and bottom app bar to sync with WebView scrolling in the Compose UI.
* Refactored the "FullScreen Video" functionality according to compose UI.
* Refactored the functionality where custom app is configured to show search placeholder in toolbar, and created the search placeholder in compose.
* Refactored the functionality where custom app is configured to show app icon in place of humbuger icon.
* Removed unused code from the reader screen.
* Refactored fullscreen mode functionality to align with Compose UI.
* Improved the `CloseAllTabs` button styling to match the app theme.
* Refactored the "Back to Top" button functionality using Compose, and enhanced its UI.
* Fixed: `Long-press` on bottom app bar buttons was not working due to `IconButton` consuming the touch event.
* Removed the unused `AnimationUtils` file.
* Fixed: Navigation history (forward and backward) was not being displayed.
* Improved the tabs UI to align with our XML-based layout. Added a border to the selected tab for better visual feedback, making it easier for users to identify the active tab.
* Added animation to smoothly scroll to the selected tab when the tab switcher is opened.
* Fixed a crash scenario when "Close All Tabs" was triggered.
* Fixed a crash that occurred when launching the app for the first time.
* Fixed an issue where the tab menu item was still visible even after all tabs were closed.
* Improved the KiwixAppBar to support custom views in menu items — enabling custom UI like the tab switcher.
* Fixed: TTS controls were not displaying correctly on the UI.
* Refactored the TTS functionality to align with the Compose UI architecture.
* Fixed: Some lint issues and improve the code quality.
* Refactored KiwixAppBar to support a string title instead of a string resource ID, allowing dynamic titles like ZIM file names.
* Fixed: ZIM file title was not appearing correctly in the toolbar.
* Refactored all snackbar-related functionalities on the reader screen.
* Updated KiwixAppBar to support an overflow menu.
* Introduced ReaderMenuState to manage menu item state dynamically for improved maintainability.
* Improved the UI of the `Reader screen` to display the tabs view properly.
* Refactored functionalities in `CoreReaderFragment`, including bottom toolbar interactions, runtime UI updates, and handling of the "No Book Open" button, etc.
* Fixed: `ImportBookmarkTest` which was failing on CI.
* Refactored UI and unit test cases according to the new codebase.
* Fixed: Selecting a ZIM file would select all ZIM files displayed on the Local Library screen.
* Fixed: `network result & language db results activate a combined network + db result`, `library marks files over 4GB as can't download if file system state says to` and `books found on filesystem are filtered by books already in db`, which sometimes fails on the CI.
* Fixed: Saved books in the library were not appearing on the Local Library screen.
* Fixed: Opening a ZIM file via the download notification was not working.
* Fixed: Selecting a ZIM file would select all ZIM files displayed on the Local Library screen.
* Improved: Migration logic now properly migrates books that were stored in the file system before introducing `ZimReaderSource`.
