Add swipe gesture to dismiss/close layered pages
Currently, to close layered pages you need to click the top left arrow button, which is quite hard to reach on a mobile device.
I propose that the animations for adding layered pages be changed from vertical one, to one sliding in from the right. Then, gestures can be implemented so that swiping right with the finger can dismiss the page without needing to reach (similar to current pagerow gesture).
As you swipe right, you should be able to see the layer underneath being revealed as the page slides off.
