I love the three finger drag on mac trackpads. Is there any way to do this on the Magic Mouse? ie Lay three fingers on the mouse and instantly drag just like on a trackpad? I know there is the doubletap+pause-then drag (drag lock) but this is a lot slower and cumbersome than fingersdown-fingersup. I have BetterTouchTool but I don't see any option for three finger drag on Magic Mouse unless I'm missing it.
