Addition of a main game setting to enable finger collision on ATMFCD.
This would simply add zone behind the screen. If your finger is in it, it would be moved back to the surface of the screen.
Buttons on the TSD seems to have a cubic hit box, but I still sometime click behind them. Mainly in high intensity combat. This might purely be a skill issue on my part, but I feel like if you miss the button, your reflex is to "click harder" and you quickly end up with your hand in the screen.
An haptic feedback (controller shake) when your finger collide with the screen could be interesting as well. Maybe. Since it could also lead you to think you've reached the button, when you haven't. Would need testing.
