OK - I think that answers the question that was floating around in my head. I am not "in the know" on style sheets... If I just don't worry about it right now, these are options that will be available in preferences later?
I would love the blue sidebar to be a (style sheet?) preference we could set, because I think that Beta, with the flag, was the best looking version yet. It was beautiful. And I agree with Texaggie that it should be the default, and let the old set-in-their ways types choose the old style in their preferences!
The dark blue/dark red colors were better for me than the electric colors... but I am neutral on the font style.
