When I click the back button, I don't want to have to wait for my finger to be released before the function activates. In other words, it'll make the phone feel a lot of snappier if it was performed on FingerDown rather than FingerDown+FingerUp. Same goes for bringing up the main menu (left of the home button), selecting options or tabs, or opening programs (yes I know holding the button is used for dragging purposes, but I could always disable the feature as and when). Lag and latency is VERY important when using a phone, and with the inherent touchscreen response already being a bit sluggish (as is the case with all mobile phones currently), we don't want to make the situation even worse. Any ideas, even it means having to root the phone?
