Group timers: each step can now have its own sound, alert style and repeat, just like a regular timer - when creating or editing a group.

Editing a running timer: with "Don't restart the timer" on, the time controls are dimmed and locked, so the countdown can't be changed by accident.

Much lighter on the battery with many timers running, smoother timer list.

Fixed: the home-screen widget could stay stuck at 00:00 after the last timer finished.
