## Major Changes
### New Jetpack Compose Architecture (1,883 LOC total)
- ComposeMainActivity.kt (370L): Main activity with Compose integration
- MainScreen.kt (322L): Root Compose screen with layout orchestration
- MainViewModel.kt (564L): MVVM state management for notes and sync
- components/NoteCard.kt (243L): Individual note card with selection support
- components/NotesList.kt (65L): LazyColumn with optimized item rendering
- components/DeleteConfirmationDialog.kt (93L): Dialog with Server/Local options
- components/EmptyState.kt (73L): Empty state UI
- components/NoteTypeFAB.kt (83L): Floating action button with note type menu
- components/SyncStatusBanner.kt (70L): Sync status indicator banner
### Material 3 & Design System
- SimpleNotesTheme.kt: Material 3 theme with Dynamic Colors (Material You)
- Full Material 3 color scheme implementation
- Dynamic color support for Android 12+ (Material You)
- Consistent design across MainActivity and SettingsActivity
### Performance Optimizations
- Upgraded Compose BOM: 2024.12.01 → 2026.01.00 (latest Jan 2026)
- Enable Strong Skipping Mode for efficient recomposition
- Async loadNotes() on IO dispatcher (no UI blocking at startup)
- LazyColumn with proper key={it.id} and contentType
- Pull-to-refresh with PullToRefreshBox
- Minimal recomposition with state separation
### Multi-Select Feature (v1.5.0)
- Long-press note to enter selection mode
- Tap additional notes to toggle selection in selection mode
- SelectionTopBar with:
* Selection counter ("X selected")
* Select All button
* Batch Delete button
- Animated checkbox indicator on selected note cards
- DeleteConfirmationDialog with Server/Local deletion options
- Fixed server deletion: deleteNoteFromServer() now properly called with 3.5s delay
### Dependency Updates
- Added org.jetbrains.kotlin.plugin.compose (Compose Compiler)
- Jetpack Compose libraries:
* androidx.compose.bom:2026.01.00
* androidx.compose.ui, material3, material-icons-extended
* androidx.activity-compose, androidx.navigation-compose
* androidx.lifecycle-runtime-compose
- All dependencies remain Apache 2.0 licensed (100% FOSS)
### Animation & Transitions
- New animation resources:
* slide_in_right.xml, slide_out_left.xml
* slide_in_left.xml, slide_out_right.xml
- Settings slide animations (left/right navigation)
- Selection mode TopBar transitions (fade + slide)
- Smooth selection checkbox appearance
### Backward Compatibility
- NoteEditorActivity (XML) still used (kept for compatibility)
- Existing database and sync functionality unchanged
- Smooth migration path for future Compose editor
### Bug Fixes
- Server deletion now executes after snackbar timeout (3.5s)
- Multi-select batch deletion with undo support
- FAB z-index fixed to ensure visibility above all content
- Scroll-to-top animation on new note creation
### Code Quality
- Removed 805-line legacy MainActivity.kt
- Clean separation of concerns: Activity → Screen → ViewModel
- Composable functions follow Material 3 guidelines
- No remember() blocks inside LazyColumn items (performance)
- Direct MaterialTheme access (Compose handles optimization)
### Manifest Changes
- Updated to use ComposeMainActivity as main launcher
- Activity transition animations configured
### Testing
- Build successful on Pixel 9 Pro XL (Android 16, 120Hz)
- Release build optimized (minified + shrinkResources)
- Multi-select UX tested
- Server deletion verified
BREAKING CHANGE: Long-press on note now enters multi-select mode instead of direct delete
