Why doesn't the default Reminder match the Due Date?
Normally when we want a reminder, it's to be reminded on the date the task is meant to be done, i.e. the due date.
So why do I have to manually type in a the same date in the reminder field?
Please make the *default* reminder match the due date, when checking the reminder checkbox.
You can also have a configurable default reminder time, e.g. 10:30am.
Then the date can be changed from the due date if needed. (Going further, you could add some drop-down defaults like '1 week before' etc. But the due date should be the starting point!)
