Animate path bar
As discussed in the GNOME Design Matrix, it would be great if the path bar animated in the following fashion:
- First, if a path is up/down the current one by any levels, the differences is animated via a left/right slide animation.
- If they are completely different paths, but both the current and next path are pinned to the sidebar, a push up/down animation is played depending on their positions in the sidebar.
- If neither of these are true, crossfade.
Here's a demo:
