I've been thinking about how the new iPads will mimic the X gestures when it already has the Dock pop-up for swiping up.
Ideally, iPhones/iPads will have the exact same gestures, but they can't, since the iPad's dock works so well.
Unless they make a full swipe up on iPad to go Home instead of the current App switcher, & introduce the half swipe up & across to access App switcher/Control Centre?
