Additional "scheduled date" beside "due date"
It would be great if there is an additional field to the due date. There might be Tasks with a due date which is in the next week, even in the next month. But for better planing it would be great to be able to schedule a task on a certain day.
In my view that is an really important feature for timemanagment!
With that simple additional field you can capture weekly and daily todo List's without changing the due date.
