With the proper gesture enabled, Lion allows using a three-finger drag to move a window. However, it only does this when the pointer is over the title bar; gesturing anywhere else in the window does a text highlight instead. Is there a hidden configuration or a hack that would allow three-finger window moving from anywhere inside the window's bounds? Thanks!
Three-finger drag isn't a gesture for "move the window"; it's a gesture for "click and drag." While there might (now or someday) be third-party software that could accomplish your desired behavior, it falls beyond the scope of a simple hidden preference.
