All hints are applied in one single commit, as a commit per hint would
result in 80+ separate commits—tihs is really just too much noise.

-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
--
-- > import XMonad.Layout.Dishes
--
-- Then edit your @layoutHook@ by adding the Dishes layout:
--
-- > myLayout = Dishes 2 (1/6) ||| Full ||| etc..
-- > main = xmonad def { layoutHook = myLayout }
--
-- For more detailed instructions on editing the layoutHook see:
