Typeable has been automatically derived for every type since GHC 7.10, so remove these obsolete derivations. This also allows us to get rid of the `DeriveDataTypeable` pragma quite naturally.

-- $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.
|
|
--
|
|
-- > ...
|
|
-- > , ((modm, xK_x ), sendMessage $ Toggle SIMPLETABBAR)
