Uses XMonad.Actions.GridSelect to display a number of actions related to window management in the center of the focused window. Actions include: Closing, maximizing, minimizing and shifting the window to another workspace.

Note: For maximizing and minimizing to actually work, you will need to integrate XMonad.Layout.Maximize and XMonad.Layout.Minimize into your setup. See the documentation of those modules for more information.

You can use this module with the following in your xmonad.hs:

   import XMonad.Actions.WindowMenu

Then add a keybinding, e.g.

   , ((modm,               xK_o ), windowMenu)
