v0.5.3 AI Phase 3 Final Integration with Phase 4 Advanced Features

v0.5.3: AI Phase 3 Final Integration with Phase 4 Advanced Features

AI Phase 3 Final Integration

Complete SuggestionsManager integration with editor component tree for seamless suggestion handling.

• Editor selection tracking for cursor position awareness
• Suggestion acceptance callbacks with automatic text insertion
• User preference state management with persistence
• Real-time suggestion display below editor content

AI Phase 4 Advanced Features

Grammar checking, context-aware writing assistance, and comprehensive analytics.

• Grammar Checking: Pattern-based detection for common errors (a/an, your/you're, its/it's) with 500ms debouncing to prevent excessive checking during fast typing
• Context-Aware Writing: Tone and vocabulary consistency analysis with 800ms debouncing for comprehensive evaluation
• Readability Scoring: Flesch-Kincaid grade level calculation with visual feedback
• User Preference Learning: Automatic inference of writing tone and vocabulary from acceptance patterns
• Suggestion Caching: 5-second TTL cache to eliminate redundant checks during editing sessions
• Analytics Tracking: Batched event tracking (10 events per send) with timestamps for suggestion acceptance and dismissal

Architecture Changes

New EnhancedEditorPanel wrapper component wraps EditorPanel with SuggestionsManager and implements debounced suggestion checking, caching, and analytics tracking.

App Store enhancements for editor selection tracking, user preference persistence, and Phase 4 feature toggles.

Performance Improvements

Debouncing strategy prevents suggestion thrashing during fast typing. Grammar checks at 500ms, context analysis at 800ms, maintaining 150ms editor update debounce. Suggestion caching with text-hash keys prevents redundant LLM calls. Batched analytics reduces network overhead.

Build Status

Zero TypeScript errors, full backward compatibility with existing EditorPanel functionality, 3,346 kB optimized renderer bundle, 11,886 modules compiled successfully.

Release v0.4.3: Keyboard & Shortcuts

Added

• Keyboard shortcut customization — Full keyboard shortcut remapping system with parseKeybinding(), validateKeybinding(), and formatKeybinding() functions for cross-platform support (Ctrl vs Cmd on Mac, Alt vs Option). Shortcuts display with platform-aware symbols (⌘, ⇧, ⌥ on Mac; Ctrl, Shift, Alt on Windows/Linux)
• Shortcut conflict detection — detectConflicts() algorithm automatically identifies duplicate keybindings across all shortcuts. Conflict warning display in KeyboardShortcutsPanel showing duplicate count and affected commands. Real-time validation prevents users from creating conflicting bindings
• Preset keyboard schemes — Three professional preset schemes: VS Code (ctrl+n, ctrl+o, ctrl+s, ctrl+shift+p for command palette), Vim (alt+b, ctrl+u, ctrl+r, shift+colon for command), Emacs (ctrl+x, ctrl+underscore, alt+w, alt+percent). One-click preset switching in UI. Each preset provides 18 pre-configured shortcuts across file/edit/view/tools/spell-check categories
• KeyboardShortcutsPanel component — Comprehensive customization UI with searchable shortcut list, category filtering (All, File, Edit, View, Tools, Spell-check), inline editing with key recording feature. Search fuzzy-matches on command name, label, and description. Preset buttons with active state indicator. Conflict detection display with warning count. Save/reset buttons for each shortcut with custom badge indicator
• ShortcutCheatSheet modal — Responsive cheat sheet modal (Ctrl+Shift+K to open) displaying all shortcuts organized by category tabs. Table layout showing command name and formatted keybinding. Overlay dismiss on background click. Responsive grid layout (auto-fit minmax 400px) for optimal viewing on different screen sizes
• Keyboard event handling — matchesKeybinding() utility accurately matches JavaScript KeyboardEvent against keybinding strings, accounting for all modifiers and cross-platform differences. Integrated into App.tsx global keyboard handler for cheat sheet trigger (Ctrl+Shift+K). Support for recording new keybindings via keyboard event capture
• Shortcut persistence — All custom shortcuts and current preset choice persist to localStorage via app-store integration. loadSetting('keyboardShortcuts', getDefaultShortcuts()) initializes with 20+ built-in shortcuts. saveSetting() on every shortcut modification ensures no data loss
• Built-in shortcuts — 20+ default shortcuts including: file operations (new, open, save, save-as), editing (undo, redo, cut, copy, paste), view (toggle-sidebar, zoom-in, zoom-out), tools (find-replace, command-palette, go-to-line), writing (spell-check-toggle, grammar-check-toggle, writing-suggestions-toggle, shortcuts-cheat-sheet)

Changed

• App store expansion — Added keyboardShortcutsOpen, shortcutCheatSheetOpen, keyboardShortcuts[], and currentShortcutPreset state properties with setters. Integrated getDefaultShortcuts() import for state initialization with localStorage persistence
• App.tsx keyboard handler — Extended global keydown handler with Ctrl+Shift+K (Cmd+Shift+K on Mac) binding to toggle shortcut cheat sheet. Added KeyboardShortcutsPanel and ShortcutCheatSheet component imports and rendering
• CSS styling architecture — Created keyboard-shortcuts-panel.css (300+ lines) with panel layout, preset buttons, search box, shortcut list, inline editor, and key recording animation. Created shortcut-cheat-sheet.css (200+ lines) with modal overlay, category tabs, table styling, and responsive grid layout
