There in "Ideas & suggestions" -forum was some talking to get more attention to Ubercart buttons.
I've seen some Ubercart shops already managed to code beautifully colored "add to cart" and "Checkout" buttons. As a non coder I suppose there's some CSS-edit needed but what file and how? (maybe this is by theme by theme, or some Ubercart files? I have Tapestry theme from Rooplethemes in my mind)
All tips appreciated.
