Aaargh, you mean it's actually altering my photos when I do that?!

So in order to have the changes take effect, one would need to initiate a full 
album rescan and update of the database, correct? Is there a way to do that, 
in the backend, if not in UI? I can probably patch the UI and add that action 
to the tools menu. I just need something to test my modifications there.

Well, if there's a string freeze, I hope you can push a change to the "Update 
Metadata Database" before. It's really very much misleading. "Update Image 
Metadata" would be way more appropriate.
