Now that we have a double tap gesture on the 6's home button, what are the odds Apple intends to extend the home button's touch functionality? Maybe make the button a tiny bit bigger, and you could conceivably use it for gaming, scrolling, dismissing notifications on the lock screen, etc.
Yeah, we're probably going to have to wait for a jailbreak to get the feature in iOS 8. And maybe if we're lucky Apple will make the touch sensitive home button more customizable in iOS 9.
