Hey brett, think about having a small control panel addition so one can customise colours a little eariser? Well, the colours that would be interesting to play with (you know I have):
Background Colour
Border Colour
Quota Bar Colour
Quota "Widget" Colour
I'm sure there is others :x... Wouldn't really need to have a cpannel section per say, possibly just have it defined in the wordlet files or style settings...
