 - **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.
+- **Files, sturdier**: the Seafile pass-through gives Seafile 30 seconds to answer (2 minutes to start a file transfer), retries a failed read twice, says plainly when Seafile is slow or down, and stops reading from Seafile as soon as you close a download. In the app, an expired Seafile sign-in asks for your password again in a sheet and then carries on where you were. Each folder you open is saved (names, sizes, dates) so it shows instantly while the real list loads, and stays visible with a note when you are offline or Seafile cannot be reached; very large folders show 300 rows at a time with Show more, and the scroll position comes back when you return. Uploads wait for the connection instead of failing, retry with growing pauses (5 tries), and when a name is already there you choose Replace (the old version stays in the file's history), Keep both, Skip or Cancel. Deleting offers **Undo** (from Seafile's recycle bin), and **Recycle bin** in the folder menu (the three-dots button in the toolbar) restores anything deleted from the library. The same menu has **Search this library** and **Download as zip** (also in Select mode and on a folder's menu). **Share links** now offer a password and an expiry, list the links that already exist and can delete them. Text files (txt, md, json, csv, logs, config files, code) open in a viewer, and small ones can be edited and saved there. Not included: resumable chunked uploads (a dropped connection restarts that file; I could not confirm Seafile's chunk protocol without a server to test), editing files over 256 KB in the viewer. The recycle bin, Undo, zip, share options and text saving use Seafile's documented API but have only been tried against a fake Seafile, not a real one.
 - **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.
