-- $usage
-- To use this module with "XMonad.Layout.MultiToggle", add the @SIMPLETABBAR@
-- to your layout For example, from a basic layout like
--
-- > layout = tiled ||| Full
--
-- Add @SIMPLETABBAR@ by changing it this to
--
-- > layout = mkToggle (single SIMPLETABBAR) (tiled ||| Full)
--
-- You can now dynamically toggle the 'XMonad.Layout.TabBarDecoration'
-- transformation by adding a key binding such as @mod-x@ as follows.
