Forgive me, but what does this do? I just tested it out, and it appears that it's not doing anything.
But there again, it could be because I have this app installed. I am just exploring all of the features. Features that I knew that Macs have, but never played around with because it required me using keyboard keys that I would never remember.
Anyways, you could try it out. It's free and it includes a ton of features. Including Windows 7 "window snap feature".
With this setting in conjuction with the System Preferences > Touchpad > Point & Click settings it allows you to perform any drag and drop action that you require with one or three fingers, including dragging windows and highlight text etc.
I don't use Better Touch Tool. It may have a similar setting or it may conflict with setting.
