Good point! I will double check the gestures, to see if I can make it work that only part of the gestures need to be disabled to get full swipe to go back.
As for swiping the other way to go forward; I would absolutely love to implement this, since this was also one of my favourite features. But this isn't native behaviour and means I'd have to implement my own navigation logic from the ground up. The harsh reality is therefor that I don't see this happening in the near future :(
