Feature: Animate non-shared elements by moving them in- or out of the screen

For starters, thanks for this project, it's super awesome.

One thing I'm having trouble with myself and maybe others have as well? Is that if I have two different screens, each with their own layout, i.e. buttons, images, but SOME shared elements, is it possible to move and fade the elements on the new screen that are not shared?

The fade part is actually doable, but I can't seem to get them to move. Anyone have any tricks they've found for something like this?

The one (bad) idea I've had is to include all the elements in the first screen at their starting positions. This seems like it would get very messy.

Thanks!

No files, tests, or entry points are named in the issue. First locate the existing shared-element transition implementation and examples, then determine whether non-shared elements can be moved and faded during screen changes; done should include a defined behavior and verification for both directions.
