+# TODO - Future Improvements
+
+## High Priority
+
+### Unsaved Note Switching
+**Current Behavior:** When a note has unsaved changes, switching to another note is completely blocked. User must either save or discard changes first.
+
+**Proposed Improvement:** Implement local session storage for unsaved changes:
+- Store unsaved note content in browser's sessionStorage/localStorage
+- Allow switching between notes without losing unsaved changes
+- Each note maintains its own unsaved state independently
+- Unsaved changes persist across note switches but don't trigger server sync
+- Visual indicator shows which notes have unsaved local changes
+- Only sync with server when user explicitly saves
+
+**Benefits:**
+- More flexible editing workflow
+- Can work on multiple notes simultaneously
+- No data loss when switching notes
+- Better matches user expectations from modern editors
+
+**Technical Approach:**
+- Use Map/Object to store unsaved changes per note ID
+- Key: note ID, Value: { title, content, timestamp }
+- Load from local storage on note switch
+- Clear local storage on explicit save or discard
+- Add visual indicator (dot/asterisk) on notes with local changes
+
+### PDF Export Styling
+**Current Issue:** With custom Google Fonts in place, PDF export produces broken layout and styling. The jsPDF html() method doesn't properly handle web fonts and complex CSS.
+
+**Needs Investigation:**
+- jsPDF may not support external web fonts properly
+- May need to embed fonts or use fallback system fonts for PDF
+- Consider alternative approaches: html2canvas, puppeteer, or server-side PDF generation
+- Ensure proper markdown rendering with headings, lists, code blocks, etc.
+- Maintain consistent styling between preview and PDF output
+- Consider bundling Google Fonts locally for offline support and better PDF rendering
+
+### Offline Mode
+**Current Issue:** App fails when internet connection is unavailable. No local caching, no change queuing, no sync on reconnect.
+
+**Required Features:**
+- Local-first storage of all notes (IndexedDB or localStorage)
+- Work offline seamlessly - create, edit, delete notes
+- Queue changes when offline for later sync
+- Detect connection restore and push queued changes
+- Conflict resolution when note changed both locally and on server
+- Visual indicator showing online/offline status
+- Show which notes have pending sync
+
+**Technical Approach:**
+- Cache all notes locally on successful fetch
+- Intercept all API calls - if offline, work with local cache
+- Maintain a sync queue: { noteId, action, timestamp, data }
+- Use navigator.onLine and 'online'/'offline' events for detection
+- On reconnect: process queue in order, handle conflicts
+- Conflict strategy: last-write-wins or prompt user
+
+**Synergy with Other Features:**
+- Pairs well with "Unsaved Note Switching" (both need local storage)
+- Bundled fonts ensure app works fully offline

+
+## Medium Priority
+
+### Other Improvements
+- Add keyboard shortcuts (Cmd+S for save, Cmd+N for new note, etc.)
+- Implement note search within content (not just titles)
+- Add tags/labels system as alternative to categories
+- Export multiple notes at once
+- Import notes from other formats (Markdown files, etc.)
+
+---
+
+## Low Priority
+
+### Nice to Have
+- Note templates
+- Rich text paste handling
+- ~~Image upload/embedding support~~ ✅ (viewing attachments works, upload TBD)
+- Note linking (wiki-style)
+- Version history/undo for saved notes
+- Customizable editor themes
+- Font size adjustment
