Thanks @nirav7707!

After testing, I pushed a few small adaptations.

We don't have a color change when viewing a synced element, I think we should do the same for the unsynced — that way it's a bit clearer that there is a color difference, and they're also more consistent.

Should we fix the hover color of the < Back button while we're here?

Sure thing. I made it $gray-900 in 7dfe9cc.

Nice. I like the subtle animation.
