Yeah, i'm crazy. I like doing things my own way, and tabbed browsing goes completely against that.
I. Hate. Change.
Besides, half the point of IE7 is to try and get rid of the "screen creep" that can occur thanks to toolbars etc. As far as I care though, the tabs are adding to it!
Look how much space they're taking up! They're easily as much as a toobar themself! Why isn't there an option to turn them off?!
