Gesture to minimize window in Gnome Shell

view full story

http://askubuntu.com – I have Ubuntu 12.04 with Gnome Shell chosen as Desktop Manager. I'm getting used to how the windows are resized as they are dragged on some edge of the screen (e.g. maximized when dragged on the top, split by half horizontally and right-aligned when dragged on the right ecc), but I'd really like a similar way to minimize the windows when dragged on the bottom, for example. I know this is possible with a custom shortcut, but, I'd like to do that with just a mouse. So, is it possible? :) (HowTos)
