Move and Hide

I wrote a little patch for wmctrl, to show/hide the window decorations of a window via commandline, perhaps some of you will find this helpful.
And this script will output the geometry for a window to place it on different monitors in multihead systems. By now it supports only some configurations (including a big cube of 4 monitors or 4 monitors in a line), perhaps i will improve it's functions in a while, but right now it does exactly what i want.
Example usage:

will hide the windows decoration.

will bring back the windows decoration.

will place a window on the second screen (if the configuration is done well and the application supports -geometry).
