I didn’t have much time to look around but it looks good.
I like the clock function, but there are times when that is the only item so it leaves a blank column below it squashing the remainder of the page, depends on how big the browser window and resolution are of course.
Nice idea with a tool bar, I don’t know if you can do it to drop the clock and other toolbar items down as you scroll down so there wouldn’t be any expanse of white space.
Check out this site, http://noscript.net/ our well known firefox extension, they use something to move the three buttons on the right down as you scroll down the page. I don’t know if you can check out the page source for some idea how they did it.
