I like the Quick_Jump, and use it to add gas tanks, but AFAIAC, not a big deal.

I am guessing you are trying to save bandwith ?

When I look at the category icons, I always imagine the color blocks that make up the nav bar, sitting on a piece of glass. I wonder if the GreenHybrid/the auto evolves logo could be put under the nav bar, skewed so that it looks as though the logo is at 90 degrees to the blocks; on (or under) the glass, as it were. If that looked good, you could get rid of the top header entirely.

Can the quick jump menu be changes to drop-down menus from the nav bar ?
