When I have a task due at a specific time, I would like the ability to postpone it to a later time, instead of the next day. I want the ability to quickly choose to postpone 15 minutes, 30 minutes, an hour, or enter a new time.

For example, if I have a reminder to give my dog his medicine at 6pm and I'm occupied at 6pm, I want another reminder later that day, not the next day.
