Option to star your top 3 tasks of the day (as a reminder).
Maybe at the end of the night (or the scheduled time) the app will give a header reminder that asks: "Did you complete your top 3 tasks of the day (or actual: "May 10"). That's all.

I think you should just add starred tasks, period. An unlimited amount of stars. This would be useful, because whenever I have overdue assignments, it pushes down the assignments due soon. Most people want to get the work due for the next day done first before they go back and finish missing or overdue work.
