Using three finger swipe
I liked having a three finger swipe up to spread all open windows and having a three finger swipe down minimize all windows. Is there a way I can implement this in Ubuntu 12.04?
Here's some solution, it works for me (Ubuntu 12.04) with 4 finger drag but you can customize it. Although there are some bugs with the 3 finger drag because ubuntu has some default gestures written in the source code.
