Allow to style the forum in ACP:
Bachground colors, BG pictures, text colors .....
So you can coohse a style which you think it is nice and change the colors, pictures etc. to tune ist to your needs without changing style datas directly in the style.
Maybe an extra tool on the website to create an own style, where you van select the parts and change color stylings etc. Something like the themeroller for JQUI.
