# Improvements & Known Issues

## Critical Bugs

- [x] **Photos 404 in Docker** — serve via `/api/photos/[filename]` from `UPLOAD_DIR=/data/uploads`
- [x] **WHO curves invisible when baby has measurements** — `connectNulls` on percentile Lines
- [x] **Symptom icon missing** — `Activity` not in event-icon map
- [x] **Default duration missing** — events saved without timer now get per-type default duration

## UI/UX Improvements

### Dashboard
- [x] **Empty state for new users** — onboarding callout when no events today
- [ ] **Active timers show which baby** — add baby name badge if multiple babies in family

### Growth
- [x] **Single-measurement chart** — shows point + WHO curves (was blank until 2+ points)
- [x] **"PC" label** — expanded to "PC — Périmètre crânien (cm)"
- [x] **WHO percentile ⓘ tooltip** — explains P50/P3-P97
- [x] **Date field defaults to today** in add-measurement form
- [ ] **PDF export percentile rank** — show WHO band (e.g. P25–P50) per row in PDF table

### Stats
- [x] **Heatmap legend** — shows actual counts (0 1 2 3 4+)
- [x] **Sleep timeline label** — "Fenêtre 19h – 11h"
- [ ] **Chart zero-data gaps** — distinguish "no data" vs "zero events" visually

### Timeline
- [x] **Filter state sticky** — persisted in URL param `?type=...`
- [x] **Inline note save feedback** — ✓ flash after blur
- [x] **Photo thumbnail clickable** — opens in new tab
- [ ] **Select mode indicator** — show "3 sélectionnés · Supprimer" counter badge

### Photos
- [x] **Lightbox wraps** — next on last → first, prev on first → last
- [ ] **Delete from lightbox** — trash icon removes photo from event metadata

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

### Notes
- [x] **Unsaved indicator** — amber dot while dirty, green ✓ after save
- [ ] **Date jump input** — calendar picker to jump to any date (not just nav arrows)

### Milestones
- [x] **Sort by date** within month group

### Settings
- [x] **Pushover key eye toggle** — show/hide pasted key
- [x] **API key delete confirmation** — shows key name in confirm dialog
- [x] **Sections collapsible** — SectionCard accordion
- [ ] **Invite link TTL** — show expiry date next to copy-link button

### Event Modal
- [x] **Timer resume indicator** — "Reprise du chronomètre" when loaded from localStorage
- [x] **Milk lot hint** — "Sélectionnez un lot — il sera marqué comme utilisé"
- [x] **Photo size client-side validation** — 5MB guard before upload

### Navigation
- [ ] **Baby switcher `aria-label`** — accessibility label on select
- [ ] **Unsaved state warning** — prompt before leaving dirty notes page
