Instead of having to define the precise time when sending later, an additional option to send later with a timer would be nice. See: I want to send in 5min, let's set a timer to 5min and go, instead of having to calculate what time it will be in 5min and the time I calculate and set the clock widget to it, it's already 1 minute lost. Maybe easier and might also better fit people's need, which might not be to schedule a sending bitt to delay it.
