It's a program that lets you view the skin without having to fire up main LFS exe every time. You just run it on a window and check how the skin looks, do some work, and see again.
i've used the viewer before... like i said earlier, just because i think it looks good doesn't mean it really is... i'd probably drive it as long as its not purple or hot pink...
i want to keep the green... that said, have any other colour substitutions?
