-- $usage
-- You can use this module with the following in your
-- @~\/.xmonad\/xmonad.hs@:
--
-- > import XMonad.Layout.SimpleFloat
--
-- Then edit your @layoutHook@ by adding the SimpleFloat layout:
--
-- > myLayout = simpleFloat ||| Full ||| etc..
-- > main = xmonad def { layoutHook = myLayout }
--
-- For more detailed instructions on editing the layoutHook see:
--
-- "XMonad.Doc.Extending#Editing_the_layout_hook"
-- | A simple floating layout where every window is placed according
-- to the window's initial attributes.
--
-- This version is decorated with the 'SimpleDecoration' style.
