Improvement - Sync reviewed files with commits

[frejfrej]

In the diff view, your plugin helps see which file was reviewed. It would be nice to have the commits whose files have been been "Done reviewing" marked as "Done reviewing" too.
Also the other way around: allow the user to mark a commit as "Done reviewing", which would in turn update the Diff view.

I think I looked into something similar to this, but there wasn't enough info about commits available in the UI to make it possible. Might take another look at it.
