I should add a check for errors on that and avoid moving, and ideally also have it rollback changes if it moves one, but fails on the other (like if for some reason a file already exists with the target name, or it fails to create a folder, etc.)
Hair and Fur are considered one tag, mainly because a given race can only have one of those, none of them have both a skin and a fur color.
I do like the idea though of marking colors that are never normally picked by the game for selected race(s). Maybe mark it red if none of the selected races can have that color, yellow if some of them can (in case someone is applying multiple for some reason).
I don't see adding a copy option instead of move. You can achieve this outside the editor easily by only working on a copy of the files, which honestly I'd recommend anyways.
"Her skin is a tanned". Or you are meaning random portrait generator? Sorry, i have feeling i didnt understand you =D
