-- $usage
-- This module provides actions (that can be set as keybindings)
-- to automatically send the next spawned window(s) to the floating
-- layer.
--
-- You can use it by including the following in your @~\/.xmonad\/xmonad.hs@:
--
-- > import XMonad.Hooks.FloatNext
--
-- and adding 'floatNextHook' to your 'ManageHook':
--
-- > myManageHook = floatNextHook <+> manageHook def
--
-- The 'floatNext' and 'toggleFloatNext' functions can be used in key
-- bindings to float the next spawned window:
--
-- > , ((modm, xK_e), toggleFloatNext)
--
-- 'floatAllNew' and 'toggleFloatAllNew' are similar but float all
-- spawned windows until disabled again.
--
-- > , ((modm, xK_r), toggleFloatAllNew)

-- | This 'ManageHook' will selectively float windows as set
-- by 'floatNext' and 'floatAllNew'.

-- $pp
-- The following functions are used to display the current
-- state of 'floatNext' and 'floatAllNew' in your
-- "XMonad.Hooks.StatusBar.PP".
-- 'willFloatNextPP' and 'willFloatAllNewPP' should be added
-- to the 'XMonad.Hooks.StatusBar.PP.ppExtras' field of your
-- "XMonad.Hooks.StatusBar.PP".
--
-- Use 'runLogHook' to refresh the output of your 'logHook', so
-- that the effects of a 'floatNext'/... will be visible
-- immediately:
--
-- > , ((modm, xK_e), toggleFloatNext >> runLogHook)
--
-- The @String -> String@ parameters to 'willFloatNextPP' and
-- 'willFloatAllNewPP' will be applied to their output, you
-- can use them to set the text color, etc., or you can just
-- pass them 'id'.
