I think you provided too little information after the whole "are these horizontal lines suppose to be here" topic and exchange.
I think the current space is fine.
As for CM6, I've started a
mock of that as well
With a few days off I should get it done! I <s>'d out the menu options that shouldn't be included.
Since we all seem to want different colours, I plan to make the theme/style completly relient on the background color for everything. Need a lighter colour for a font? Just use a light gray and lower the opacity. That'll allow easy change of the background colour to just about any hex value the users desire. But there will be some style-side affects. I believe, i.e. not very vivid font/text.
Not sure how well it'll work in practice but in theory it sounds great! I haven't added that part of the idea to the CSS & HTML, so don't go looking for it!
If anybody wants to start a mock of their own
