 ### Added
+- A custom snooze duration. The **Snooze duration** setting (Settings →
+  Notifications) gains a **Custom…** option next to the minute presets: pick any
+  amount and switch between minutes and hours, so a snoozed reminder comes back
+  after exactly the delay you want instead of only a preset one ([#40]).
 - Move an event to another calendar. When editing an existing event, the
   calendar row is now tappable — pick a different calendar and saving moves the
   event across, instead of having to delete it and recreate it elsewhere.
