Bring back roller-dials!
My philosophy is that touchscreens are meant to be touched, not necessarily emulate mechanical buttons. (e.g. Swype, not type.) So when more interfaces started using rolling dials with inertia, I was completely onboard.
Seems like in this case, you could have roller dials and the plus/minus buttons. However, the manual typing of times would be more difficult to incorporate. Then again, we're only talking about one dial with twelve positions, and one with sixty.

Good idea...but PLEASE if you implement this, make an option in the settings and not a forced change. I am very used to the way it is now and will probably prefer to stick with that
