A simple, skin-tone slider so simple Chim-Chim the Primate can use it.
Title says it all. A helpful forum member pointed me at a good introductory page to learn the basics of Surfaces, but the assorted morphs in the Evolution bundles make me wonder if there isn't a way to create tool that would provide a basic and simple color slider for human skin tones, which could then be fine-tuned via Surfaces after you got to the neighborhood you wanted. Kind of like I've seen in countless MMO's and RPG's which offered character customization.
I'd buy the hell out of that.
