I saw this Mac preference pane app in action today, and I was blown away. I am not at my Mac, but this is something I plan on installing the moment I get home.
You can create custom gestures to do all sorts of things, such as:
- Three finger tap to close tab.
- Three finger tap to open link in new window
- Gesture to fullscreen an app
- Gesture for positioning apps
And so much more. Very cool tool.
