- Recurrence picker (Daily/Weekly/Monthly/Yearly, interval, end condition) for
both events and tasks, backed by a real RRULE. Fixes a latent bug from the
prior RRULE-preservation change: editing a recurring item was writing the
resolved *next occurrence* back as the master DTSTART, silently shifting the
whole series forward on every edit - start/end/due are now correctly
read-only for recurring items instead.
- Periodic background sync (WorkManager, ~30 min, network-gated) so widgets
stay fresh without opening the app; auto-refresh on app open too.
- Tasks widget now renders the same parent/child tree as the in-app Tasks
screen (util/TaskTree.kt shared by both) instead of a flat due-date list.
- Conflict resolution: a stale save (HTTP 412) shows both versions and lets
you keep your edit or take theirs, instead of just an error banner.
- First test suite for the project (IcsMapperTest, TaskTreeTest).
One app for both events and tasks, talking directly to Nextcloud's CalDAV
endpoint - no DAVx5, no Google Play Services, no third-party services.
Encrypted at rest (SQLCipher DB, EncryptedSharedPreferences, Keystore-backed
widget state), HTTPS-only networking, home screen widgets, reminders,
subtasks, and full VTODO field support (status/priority/%complete/location/url).
