You're free to change the regex and list for the skin colors. I left it as-is to allow someone to choose which tag from the list, even if it's a bit unintuitive currently.
Enter applies now, and escape resets. Additionally, instead of coloring things in the list, I just added checkbox filters for race, hair, skin, tits, and ass missing. Check the box, and it filters the list to only the ones missing the selected attributes.
I think this allows for a good workflow, can filter to everything missing tits, have mouse over tits area, select tits, hit enter, hit down, select tits, hit enter, hit down, repeat. Can work through an entire list for one attribute with minimal mouse movement now.
