One thing that always bothered me about the tabs in Safari was that I could never find the keys to move from tab to tab. This new version solves that with a easy to remember key - control-tab to move to the right and control=shift=tab to move left. Very handy when comparing two webpages, and flipping back and forth without having to navigate with the mouse. What about adding a feature like W7 where two pages could snap side by side?
