Yeah, I used to do that too (and sometimes still do). Unfortunately we really don't have any way to add any space and we've discussed this here before. The "taps" on the bar or below is up to the iOS (Apple Operating System) and we don't have a way to change the way that works. I've just trained myself to be careful and always tap a bit on the lower side of the Timer button. The timer (green or grey) section is a button. There is nothing that can be changed there.
