If you are running ubuntu 12.04(precise) and one thing you might have noticed from your unity is missing Dodge Windows behavior.
Another feature users really like is the ability to be able to click a program's icon on the Launcher and minimize/unminimize that window. Jonathan French (ojno), the developer behind this patch, has not only made this a reality, but also got this to work in conjunction with the ‘Spread Windows' functionality. He's even set up a PPA which contains the latest Unity and his patch to make it easier for end-users to get it.
