Maximize to available area of screen....

When people have windows on there screen many like to place ther chat or other object to the right or left.... then adjust many things to get all the other windows to fit in the screen well together.... having a "Maximize to available area" button or feature would be nice.
Perhaps a Shift and then click on Maximize or Center click on MAximize would be a way the we don't have to break the gui setup with yet another confusing button in the upper right corner.
I think this would be a great usibility feature in compiz.
