Reordering API For HdyDeck
HdyDeck is a great tool for making swipeable views, but it breaks down if you have multiple "layers" of views.
An example: In Store, we have apps. From an app page there can be suggested apps from the same author. If you click on that, you go to the page. The back button will refresh with the last app, and if no last app exists then it will take you to the main page.
Currently, if we want to implement this with HdyDeck and still being swipeable, we'd need to add infinite pages to the HdyDeck - which doesn't bode well for performance.
If HdyDeck had reordering, we could do something like this diagram (courtesy of @ZanderBrown):
