Store & re-render optimization:
- TripPlannerPage uses selective Zustand selectors instead of full store
- placesSlice only updates affected days on place update/delete
- Route calculation only reacts to selected day's assignments
- DayPlanSidebar uses stable action refs instead of full store
Map marker performance:
- Shared photoService for PlaceAvatar and MapView (single cache, no duplicate requests)
- Client-side base64 thumbnail generation via canvas (CORS-safe for Wikimedia)
- Map markers use base64 data URL <img> tags for smooth zoom (no external image decode)
- Sidebar uses same base64 thumbnails with IntersectionObserver for visible-first loading
- Icon cache prevents duplicate L.divIcon creation
- MarkerClusterGroup with animate:false and optimized chunk settings
- Photo fetch deduplication and batched state updates
Server optimizations:
- Wikimedia image size reduced to 400px (from 600px)
- Photo cache: 5min TTL for errors (was 12h), prevents stale 404 caching
- Removed unused image-proxy endpoint
UX improvements:
- Splash screen with plane animation during initial photo preload
- Markdown rendering in DayPlanSidebar place descriptions
- Missing i18n keys added, all 12 languages synced to 1376 keys
On mobile/touch devices, Leaflet tooltips disappear immediately on tap
since there is no hover state. This makes the info bubble permanent for
the selected marker on touch devices so it stays readable.
Fixes#249
- Category filter is now a multi-select dropdown with checkboxes
- PlaceAvatar: replace 200ms polling intervals with event-based
notification + React.memo for major performance improvement
- Map photo fetches: concurrency limited to 3 + lazy loading on images
- PlacesSidebar: content-visibility + useMemo for smooth scrolling
- Accommodation labels: check-out now appears before check-in on same day
- Timed places auto-sort chronologically when time is added
Live location:
- Crosshair button on the map toggles GPS tracking
- Blue dot shows live position with accuracy circle (<500m)
- Uses watchPosition for continuous updates
- Button turns blue when active, click again to stop
Auto-sort:
- Places with a time now auto-sort chronologically among other
timed items (transports, other timed places)
- Adding a time to a place immediately moves it to the correct
position in the timeline
- Untimed places keep their manual order_index
