CSF: The best trackpad gesture
The best trackpad gesture isn't found in System Preferences > Trackpad. It's in Accessibility.
Select Mouse & Trackpad on the left, then Trackpad Options... on the right. Then Enable dragging with three finger drag.
Now, to move a window, there's no need to click -- just put three fingers on your trackpad when over the window handle, and it moves!
Ok, maybe not the best, but I sure like it, and really missed it when I added a Trackpad to my iMac. Had to go on a hunt to reveal how I'd added it to my work MBPr...
Whoa. I love this. Thanks for sharing!
For @macps or anyone else who wants to restore the default, app-switcher functionality, go to System Preferences > Trackpad > More Gestures and re-enable Swipe between full-screen apps.
