 - **Links**: your own bookmarks page. Add a name, address and optional group; filter as you type; opens in a new tab. Saved with your settings on the server, private to you, same on every device. Only http(s) addresses are accepted.
 - **Security and backups**: every response carries `nosniff`, a `frame-ancestors 'self'` policy and a same-origin referrer policy; writes that come from another website are refused; JSON files are written atomically (temp file, then rename). Admins get **Settings -> Storage -> Download a backup** (a .tar.gz of `/data`; keep it private). `/healthz` answers without signing in and the container has a health check. In-app OnlyOffice editing now requires `ONLYOFFICE_JWT_SECRET` (or `ALLOW_UNSIGNED_OO=1` for testing). `npm test` runs every test script; CI also runs `npm audit`.
+- **Planner and grouped menu**: Calendar and Tasks are one menu entry, **Planner**, with a Calendar | Tasks switch at the top (each still needs its own permission in Settings -> People, and `#/calendar` and `#/tasks` still work as addresses). Tasks with a due date appear on the calendar (month chips, week/day all-day strip, agenda) with a tick to complete them; tapping one opens the task. The menu, the phone "More" sheet and the Home tiles are grouped by kind: Work (Planner, Files, Office, Links), Communicate (Mail, Signal), Media (Music, Audiobooks, Podcast, Podcast Admin), with Home/Search at the top and Settings at the bottom.
 - **Command palette and quick add**: press **Ctrl/Cmd-K** anywhere (or the Command palette button on Home) to jump to any page, create things, open a saved link or find a task/event. Typing a sentence offers **Add task**, and understands a date at the end ("Call mom tomorrow", "Pay rent in 3 days", "Dentist fri", "2026-12-25"). **Quick add** on Home does the same plus new event and new link. Search also finds your links.
 - **Tasks**: repeating tasks (daily, weekdays, weekly, monthly, yearly; finishing one moves it to its next date) and one level of subtasks, in NE Hub lists (iCloud reminder lists stay as Apple stores them).
 - **Calendar**: Month, Week, Day and Agenda. Week and Day show a time grid with overlapping events side by side, an all-day strip and a "now" line; tap an empty slot to add an event.
