Suggestion: touch screen support

I'm not sure if this is the right place to post something like this, but here goes.

I have a small touch-enabled laptop. The ability buttons are very easily reachable on the screen, but touching them on the screen has no effect at all. It would also be nice to be able to ping with touch. Mouse and (maybe) keyboard would still be necessary, but having touch-screen support as an addition (so that it wouldn't change the gameplay for regular mouse+keyboard players) would make it possible to ping without shifting your focus with the mouse (while escaping from a tough situation for example). If it would get implemented, I think it would make the most sense to make it so that when you touch the screen, it wouldn't hide or move your mouse cursor, and the 2 devices can be used at the same time. There are definitely more situations where touch screen could be helpful (make store touch-friendly for example?)
