Current behavior:
> Click "Deadline," calendar pops up
> Click on the date wanted
> Click "OK" on the calendar, calendar disappears
> Click "Save" to save the new deadline

Behavior suggested:
> Click "Deadline," calendar pops up
> If a deadline already exists
>> nothing different
> else if no current deadline assigned
>> Click on the date wanted, new deadline clicked appears immediately, the calendar window doesn't disappear
>> Click "OK" and it will save the new dead line


I suggest this feature because, a couple of times, I have clicked at the deadline I wanted, but it doesn't got saved because I am not clicking "OK" on the calendar afterwards, which is unnecessary if there was no original deadline.
