Undo moderation actions and disable nickname changes

I randomly came across a thought leading from one of my buds on a server I mod for being distressed about receiving a nickname change they didn't want done, and it reminded me of the idea that you could check audit logs and undo/redo changes mods made, such as removing or adding a channel, undoing and redoing nickname changes, etc etc, and on a similar note, add the ability to disable people changing your nickname in certain servers, though it may cause problems with people with inappropriate names, so possibly add a setting depending on the server to override that setting? Though there may be even more issues with such ideas, it was just something I figured more people than just me would possibly be interested in seeing
