Colicab-d, cool idea.
Any thoughts on modifying it so that it'll recognize what the current style is and then setting the new style based upon it? To clarify, if I have two completly different skins installed and each of them have a fixed & liquid option then there'd be four skins all together (eq: 1, 2, 3, 4). If the current style is "1" and if the resolution is X then use style "2" else if the current style is "3" and resolution is X then use style "4".
For boards that only use one style this script will be pretty nice as is. I'm one of those geeks, though, that have several different ones.
