 - **Daily Briefing** — the primary screen; opens on launch. Shows your AI-compiled morning digest (tasks, calendar, weather, RSS) with a full conversation you can reply to inline. Refresh manually or browse past briefings from the overflow menu.
 - **Quick Capture** — always-visible input bar above all tabs. Type a note or task and submit; multiple captures queue sequentially so the input is never blocked. Falls back to offline persistence when the server is unreachable.
-- **Library** — unified browsable list of notes, tasks, and projects with filter pills (All · Notes · Tasks · Projects). Tasks have a secondary status sub-filter and a tappable status icon to cycle todo → in progress → done without opening the editor. Inline search filters results live.
+- **Knowledge** — unified browsable feed of notes, people, places, lists, and tasks across six filter tabs. Tag filters, inline search (debounced), and two-tier pagination (ID list → batch hydration). Tasks load from `/api/tasks` directly and are fully integrated with the knowledge feed.
-- **Chat** — streaming AI conversations with real-time SSE display. Tap + to start a new conversation or open an existing one.
+- **Chat** — streaming AI conversations with real-time SSE display, including live tool-use status notifications (e.g. "Calling create_note…"). Tap + to start a new conversation or open an existing one.
+- **Calendar** — month strip + daily agenda view backed by the server's internal event store. Full event CRUD with a modal form: title, all-day toggle, start/end date+time pickers, repeat (None/Daily/Weekly/Monthly/Yearly), description, location, and colour chips. Custom RRULE strings are preserved read-only.
+- **News** — RSS article feed with per-feed filtering and reactions. Tap "Discuss" to open any article in a new chat conversation.
+- **Projects** — browse and edit projects; tap a project to see its milestone-grouped task list.
+- **Voice I/O** — tap the microphone in the capture bar or chat to dictate. Server-side STT transcribes audio; TTS reads assistant replies aloud in voice mode.
 - **Note & task editing** — full Markdown editor for notes, task editor with due date, priority, project, and milestone assignment.
 - **OAuth / SSO** — authenticates via your server's OIDC provider; local username/password login also supported if enabled server-side.
 - **Session persistence** — stays logged in across restarts via a persistent cookie jar.
+- **Auto-refresh** — data refreshes automatically when the app returns to the foreground (throttled to once per 5 minutes) and when switching between shell tabs.
 - **Auto-update** — checks your Forgejo releases on launch and prompts to download and install new APKs in-app.
