Window Stacks

Have the ability to create window stacks. For example in 'show all windows' mode be able to group the windows into containers called 'stacks'. All the windows in a stack will share the same dimensions and coordinates. Only one window, the one at the top, can be visible at the same time. Moving the top window will move the entire stack, resizing the window will resize the entire stack. Switching between windows in a stack is fast if middle clicking the titlebar is set to push the window to the bottom, window switching can be set also to a scrolling event on the titlebar.
