-- This module provides a method to cease management of a window, without
-- unmapping it.  This is especially useful for applications like kicker and
-- gnome-panel.
--
-- To make a panel display correctly with xmonad:
--
--  * Determine the pixel size of the panel, add that value to defaultGaps
--
--  * Launch the panel
--
--  * Give the panel window focus, then press mod-d
--
--  * Convince the panel to move\/resize to the correct location.  Changing the
--  panel's position setting several times seems to work.

--
-- And add a keybinding to it:
--
-- > , ((modMask,               xK_d     ), withFocused demanage)
--

-- %import XMonad.Actions.DeManage
-- %keybind , ((modMask,               xK_d     ), withFocused demanage)
