Instructions on how to get this are in the comments.
I was bored today, so I started learning javascript. I decided I wanted a better DU toolbar; here's the proof-of-concept:

(I also changed the Search button to go straight to Advanced Search, but you can't see that in a picture)
Javascript is pretty easy - I figure on making cooler things happen, like a completely individually configurable toolbar. I'm also thinking of putting the toolbar in its own frame (ie, when you scroll down a page, the toolbar doesn't disappear on you.)
I just thought I see if any of you folks were interested in anything along these line, and I'd see what I could whip up.
Lemme know if there's anything you guys would like to see, and I'll see what I can come up with, and release the code. It's greasemonkey, so it'll only work on firefox. I think there's an IE-adapter, but I seem to recall hearing that it doesn't work so well.
