where do we find history of tag prefixin categorization?

For example when I don't actually change the tag but I do add a prefix of "artist:" or "character:" which causes the color scheme to change.

There doesn't actually seem to be a log of these changes.

It'd be kinda cool if it could be tracked somewhere so those of us who do the work of prefixing for coloring get some cred ;)

I guess in the very least when I add "artist:" I end up removing artist_request so there's a lot in that sense... sorta?

I don't think such a thing exists, but I could be wrong. Might want to look around to see if it exists, but I don't think so.

It would be a good thing to keep record of, such as if people switched categories as vandalism we'd know who was doing it, and just to give credit for those of us putting in this massive work =/
