-- A decoration that includes small buttons on both ends which invoke
-- various actions when clicked on: Show a window menu (see
-- "XMonad.Actions.WindowMenu"), minimize, maximize or close the window.
--
-- 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.
