... a way to see related edits when you're entering an edit. One of the nice features of this forum is how it pulls up possibly related posts when you're entering something. If you were getting ready to, say, change the artist credit on a recording, and you could see all the other edits that affected the AC on that recording, that would be very cool and probably helpful. Also probably challenging to implement. But even if you were entering an edit, and there were a sidebar of "here's the edit history for this entity", that would be better than nothing.

So sort of like "duplicate releases" on the release editor, but for specific entity/edit types.
