    • getNote() / getAllNotes() — Data access
  • ✅ Plugin settings panel (click ⚙️ in top bar)
  • ✅ Enable/disable plugins via toggle button
  • ✅ Example "Word Count" built-in plugin

Implementation:

  • Singleton PluginManager instance
  • Map-based plugin registry
  • Callback-based event system
  • UI for plugin management

7. Integration & UI ✅

Updated Files:

  • ✅ src/App.tsx — View mode switcher, settings panel
  • ✅ src/store/appStore.ts — ViewMode state, activeMindMap tracking
  • ✅ src/components/Editor.tsx — "Generate Mind Map" button
  • ✅ src/components/Sidebar.tsx — Mind map file support, 🧠 icon

Top Bar Features:

  • ✅ View mode toggle buttons: 📝 Editor | 🕸️ Graph | 🧠 Mind Map | 👥 CRM
  • ✅ Settings button (⚙️) opens plugin settings panel
  • ✅ Active view highlighted in blue

File Tree Enhancements:

  • ✅ .mindmap.json files shown with 🧠 icon
  • ✅ Click mind map → opens in Mind Map view

Build Status ✅

npm run build

Result: ✅ Build passes successfully
Bundle size: ~2.6MB (React Flow + D3 + ELK.js)
TypeScript: All type checks pass

Dark Theme Consistency ✅

All new components follow the existing dark theme:

  • Background: var(--bg-primary) (#1e1e2e)
  • Surface: var(--bg-surface) (#313244)
  • Text: var(--text-primary) (#cdd6f4)

All changes committed and pushed to GitHub.

What's Ready for Phase 5 (AI + Plugin Ecosystem)

Plugin Framework is Ready For:

  1. AI Assistant Plugin — Chat interface with note context
  2. Auto-tagging Plugin — ML-based tag suggestions
  3. Smart Search Plugin — Semantic search using embeddings
  4. Export Plugins — PDF, HTML, Obsidian format converters
  5. Sync Plugins — GitHub, Dropbox, iCloud sync
  6. Custom Themes Plugin — User theme system
  7. Pomodoro Timer Plugin — Focus mode with timer

AppAPI Provides:

  • ✅ Note read/write access
  • ✅ Event hooks (open/save)
  • ✅ Command registration
  • ✅ Editor extension support
  • ✅ Custom view registration

Next Steps:

  • Add plugin marketplace/discovery
  • Plugin hot-reload support
  • Plugin sandboxing/permissions
  • Official plugin SDK package

Testing Checklist

Manual Testing Required:

Knowledge Graph:

  • Load vault, switch to Graph view
  • Verify all notes appear as nodes
  • Check wiki-link edges connect correctly
  • Test node colors match tags
  • Click node → should open in editor
  • Test zoom/pan/minimap controls

Mind Map Editor:

  • Switch to Mind Map view
  • Double-click canvas → adds node
  • Double-click node → edit label
  • Drag between nodes → creates edge
  • Right-click node → test all menu options
  • Verify auto-save works
  • Close and reopen → changes persisted

Auto-Generate Mind Map:

  • Open a note with H1/H2/H3 headings
  • Click "Generate Mind Map" button
  • Verify hierarchical structure is correct
  • Check mind map opens automatically

CRM View:

  • Create notes with #person or #contact tags
  • Add frontmatter: knows: [[Name1]], [[Name2]]
  • Switch to CRM view
  • Verify only person nodes shown
  • Check relationship edges appear

Plugin System:

  • Click ⚙️ settings button
  • Verify Word Count plugin listed
  • Toggle enable/disable
  • (Future: test plugin commands)

Known Limitations

  1. Graph Performance: Large vaults (>1000 notes) may experience slowdown. Future optimization: virtualization or WebGL renderer.

  2. Mind Map Layout: Auto-generated layouts are basic. Future: more layout algorithms (radial, tree, etc.)

  3. Plugin Security: No sandboxing yet. Plugins have full access to AppAPI. Future: permission system.

  4. Offline Only: No sync between devices. Plugin framework ready for sync plugins in Phase 5.

  5. Tauri Commands: Mind map save/load requires Tauri backend write_file command (already implemented in earlier phases).
