### Added
- Reminders: Agendula now delivers your due reminders itself. A one-time setup
  step explains this and asks for notification access, and a master switch in
  Settings turns the whole thing off again.
- A Settings screen, from the gear on the overview: appearance and theme, which
  fields the task form shows, your default list, and reminder defaults.
- The overview leads with Today — a progress ring showing how much of today
  you've finished — followed by a live preview of what's coming up next.
- Search across every task, open or completed, from the top bar.
- A proper app icon.

### Changed
- A tidier top bar: no app title, with search and settings pinned to the right.
