Tasks cannot be ordered by their time. A habit not done is not shown as overdue. EDIT: I checked again to use it, but 1) Recurring task cannot be created. 2) Habits are shown like scheduled tasks. It's motivating to see habit progress instead on landing screen 3) It's more useful to see progress on habit activity instead of successful day. If we set to do 2 times a day but we could do it only once, it should show progress for a 30 day goal as 1/2 (today), 1/60 (total) instead of 0/30 or 1/30.
