Overdue recurring tasks
If I check an overdue recurring daily task - it doesnt appear today, but only tomorrow. That is absolute inconvenient!
Checking off an overdue daily task is indeed changing the date to tomorrow to avoid multiple clicks if it's overdue by many days and if you check the task off once you complete it today, the next instance is tomorrow.
