Might need to think on how best to opt-in to this (if you're scrolling down the screen, hitting a chart/map and immediately scrolling can be frustrating, especially if there isn't enough of an edge on either side to use to continue to scroll.

Sometimes maps/etc require multiple fingers to active the scrolling, for example.
