# 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
- [x] **Active timers show which baby** — baby name badge below event label
- [x] **Medication overdue** — 3 states: "Dans Xh" (orange), "Disponible" (green), "En retard de Xh" (amber)
- [x] **Feeding pattern analysis widget** — avg interval + last feed + next expected (in progress)

### 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
- [x] **PDF export percentile rank** — WHO band (e.g. P25–P50) shown next to weight

### Stats
- [x] **Heatmap legend** — shows actual counts (0 1 2 3 4+)
- [x] **Sleep timeline label** — "Fenêtre 19h – 11h"
- [x] **Event limit warning** — banner when 500-event limit hit
- [ ] **Chart zero-data gaps** — distinguish "no data" vs "zero events" visually

### Timeline
- [x] **Filter state sticky** — persisted in URL param `?type=...`
- [x] **Filter chips sticky on mobile** — `sticky top-0 z-10` container
- [x] **Loading skeleton** — skeleton cards replace spinner on first render
- [x] **Inline note save feedback** — ✓ flash after blur
- [x] **Photo thumbnail clickable** — opens in new tab
- [x] **Select mode indicator** — toggle shows "Annuler" when active

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

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

### Notes
- [x] **Unsaved indicator** — amber dot while dirty, green ✓ after save
- [x] **Date jump input** — invisible date input overlaid on label, opens native calendar
- [x] **Empty blur fix** — skip save on empty/whitespace content

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

- [x] **Photo size client-side validation** — 5MB guard before upload

### Navigation
- [x] **Baby switcher `aria-label`** — added to nav select
- [x] **Active highlight on child routes** — uses `startsWith` instead of exact match
- [x] **Sidebar grouped** — sections: Suivi / Santé / Vie du bébé / Outils (replaces flat 14-item list)
