[xmonad] [PATCH] New layout modifier: Hidden

Attached is a patch that adds a new layout modifier. It scratches an itch I had with the BinarySpacePartition layout. With the Hidden layout you can remove windows from the window set and then reinsert them in the future. When used with BinarySpacePartition, it allows you to move a window to any other part of the BSP tree. -- Peter Jones, Founder, Devalot.com Defending the honor of good code
