What I would REALLY like is if some browser would allow me to pull a tab off a tab bar, drag it to the side of my screen, and Aero Snap it to the side in one motion. I'm not aware of any browser that can do this. Right now when I happen upon two pages that I want to compare side-by-side, I need to rip the tab off the bar, let it grow into a window, then drag the window to snap it.
