Just started using this today and already notice some limitations. By the way, my specific platforms would be Web, Windows, and Android.
Would like to see the following enhancements:
*collapse & expand all tasks
*completed tasks disappear automatically (archived not deleted, etc.) and remaining outstanding tasks move up
*all sub tasks should have check boxes to mark as completed, not just 1st & 2nd tiers.
*when a task is marked as completed, automatically include date & time, similar to data & time showing in notes
