The Done 1.3 update has just landed in the App Store with the first of the new features we’ve added in response to your poll requests.
This version features a new options button on the main list screen that enables you to turn the sound effects on or off and choose how the icon badge will work. You can choose from three settings: no badge icon, all uncompleted tasks (much too depressing for me) or just your priority one tasks.
We’re already hard at work on the next update which will be either due dates or notes (whichever gets finished first!).
