Hi there (and welcome back!). Look at Viewport and AnimatedPositionBehaviours. There’s SnapToPageBoundaries, which could be what your’e after (but I haven’t used it yet).
Also check out this recent thread for a solution to a problem with the inertia:
Things get tricky if you want to swipe through pages with GUI elements, because this does not work as in iOS or Android (and as users surely expect!). If one initiates a swipe gesture over a GUI element, this activates the element. This is specially problematic with comboboxes and sliders. I’m at the moment trying to figure how to best deal with this.
