From a design perspective, I love the idea of using transitions to help users orientate themselves but this sometimes lends itself toward activating a transition depending on where you have come from not what page you are on...

For example, take a page like this one with buttons at the bottom heading left (back) or forward (onward) transitions could reinforce the effect of moving through pages organised 'like a book'. When you click next > the page could come in from the right BUT you would want the < previous button to come in from the left.

In other words, the same page displays differently depending on what button you press. Is that possible, or is it assumed that transitions are only applied to objects?

Sorry for my ignorance I am looking forward to mastering this!
