Welcome to the Lion's greatest new feature thread, where we forgo the whining, stop worrying about upgrade troubles, and talk excitedly about whatever new feature in Lion makes us the happiest. Starting today is, well, me! To me, the greatest new feature in Lion is the Magic Trackpad power. I have these gestures on it: - Pinch to Zoom - Two-finger double-tap to zoom - Flick to go forward and backward in Safari - Rotation - Swipe for spaces - Mission Control - App Expose - Launchpad - Show Desktop That's so many features from one little device, it can completely replace the mouse in terms of features! I love Two-finger double tapping most, since it gives me a good way to browse while leaning wayyy back in my chair. So, guys, what's your favorite new feature?
