# Improvements & Known Issues

## Critical Bugs

- [x] **Photos 404 in Docker** — Upload wrote to `public/uploads/` (root-owned in standalone container). Fix: serve via `/api/photos/[filename]` from configurable `UPLOAD_DIR=/data/uploads`. Mount `/data/uploads` as Docker volume.
- [x] **WHO curves invisible when baby has measurements** — `connectNulls` missing on percentile Lines; baby data rows with no p-values broke line segments.
- [x] **Symptom icon missing** — `Activity` not registered in `event-icon.tsx` icon map.
- [x] **OMS curves break when measurements exist** — same as above (connectNulls).

## UI/UX Improvements

### Dashboard
- [ ] **Empty state for new users** — show "Commencez par enregistrer un repas →" callout when no events today
- [ ] **Active timers show which baby** — add baby name if multiple babies in family

### Growth
- [ ] **Single-measurement chart** — currently blank; should show point + WHO curves + message
- [ ] **"PC" label** — expand to "Périmètre crânien (PC)" on first use
- [ ] **WHO percentile tooltip** — "P50 = médiane : 50% des bébés sont en dessous"
- [ ] **Date field defaults to today** in add-measurement form
- [ ] **PDF export percentile rank** — show baby's WHO band in PDF table

### Stats
- [ ] **Heatmap legend** — show actual count numbers (0, 1, 2, 3+) not just "Moins/Plus"
- [ ] **Sleep timeline** — label "19h → 11h" window, make configurable
- [ ] **Chart zero-data gaps** — distinguish "no data" vs "zero events" visually

### Timeline
- [ ] **Filter state sticky** — persist in URL param (`?type=BREASTFEED`)
- [ ] **Inline note save feedback** — subtle "Enregistré ✓" flash on blur
- [ ] **Photo in timeline** — make thumbnail clickable to open lightbox
- [ ] **Select mode indicator** — show "3 sélectionnés · Supprimer" counter badge

### Photos
- [ ] **Square thumbnails** — force aspect-ratio: 1/1 with object-cover
- [ ] **Lightbox wraps** — next on last → first photo; prev on first → last
- [ ] **Delete from lightbox** — trash icon in lightbox → removes photo from event metadata

### Search
- [ ] **Results clickable** — link events to `/timeline?date=YYYY-MM-DD`, notes to `/notes?date=...`
- [ ] **Result count header** — "X événements · Y notes"
- [ ] **Date/type filter chips** on search results

### Notes
- [ ] **Unsaved indicator** — show "Non enregistré" dot while textarea is dirty
- [ ] **Date jump input** — calendar picker to jump to any date (not just nav arrows)

### Milestones
- [ ] **Sort by date** within month, not creation order

### Settings
- [ ] **Pushover key eye toggle** — show/hide pasted key (copy pattern from API keys)
- [ ] **API key delete confirmation** — "This will break integrations using this key"
- [ ] **Accordion/tabs** — collapse long settings sections on mobile
- [ ] **Invite link TTL** — show expiry date next to copy-link button

### Event Modal
- [ ] **Timer resume indicator** — show "Reprise depuis 12:34" when re-opening active timer
- [ ] **Milk lot selection hint** — "Sélectionnez un lot qui sera marqué comme utilisé"
- [ ] **Photo size feedback** — client-side 5MB validation with error message

### Navigation
- [ ] **Baby switcher accessibility** — add `aria-label="Sélectionner bébé"` to select
- [ ] **Unsaved state warning** — prompt before navigating away from dirty notes

- [ ] **Teeth tracker** — visual mouth diagram, mark appearance date

- [ ] **Natural language digest** — "Emma feeds every 2h45 on average" weekly push
- [ ] **Wellness check-in** — parent self-reports sleep/mood for postpartum monitoring
