the dzen logHook stuff is already set up to show current, visible and
hidden screens in the status bar, to make it really easy to see 
the current mapping from screens to workspaces.

See Eric's config file and screenshot:

    http://haskell.org/sitewiki/images/3/3f/Glguy-config.jpg

(note the visible and current marked screens)

and a fairly fancy config file,
    http://haskell.org/haskellwiki/Xmonad/Config_archive/Eric_Mertens%27_xmonad.hs

the essence of whcih is,

    logHook            = dynamicLogWithPP $ myPP din

     
     myPP h = defaultPP
              { ppCurrent  = dzenColor "white" "#cd8b00" . pad
              , ppVisible  = dzenColor "white" "#666666" . pad
              , ppHidden   = dzenColor "black" "#cccccc" . pad

so yep.  dynamicLogWithPP with seperate colours for current, visible and
hidden.

We'll continue to improve and simplify the status bar mechanisms.
