Considering the time took between versions, I rather use darcs. I
thinks it's time to learn.

Yes, indeed with the darcs version works that way.

Thanks :)

A couple of months ago, you started a similar thread[1], it derived in
a sort-of offtopic discussion, but there were a very interesting part,
that you might find useful.

myWorkspaceCompare :: Bool -> X WorkspaceCompare
myWorkspaceCompare phy = do
    w <- gets windowset
    return $ \ a b -> case (isOnScreen a w, isOnScreen b w) of
        (True, False)  -> LT
        (False, True)  -> GT
        (True, True)   -> cmpPosition phy w a b
        (False, False) -> comparing (recentlySeen w) a b
  where
    recentlySeen w t = case findIndex (t==) $ map (W.tag .
W.workspace) (W.visible w) of
                         Just n  -> n
                         Nothing -> length (W.visible w)
    allScreens w =  W.current w : W.visible w
    isOnScreen a w  = a `elem` map (W.tag . W.workspace) (allScreens w)
    tagToSid s x = W.screen $ fromJust $ find ((== x) . W.tag . W.workspace) s
    cmpPosition False w a b = comparing       (tagToSid $ allScreens w) a b
    cmpPosition True  w a b = comparing (rect.(tagToSid $ allScreens w)) a b
      where rect i = let (Rectangle x y _ _) = screens !! fromIntegral
i in (y,x)
            screens = map (screenRect . W.screenDetail) $ sortBy
(comparing W.screen) $ W.current w : W.visible w

getSortByMyRule = mkWsSort $ myWorkspaceCompare True

That part was from Jacek Generowitz xmonad.hs[2], and does basically
what it says in the comment. Sadly, the whole file expired, so I could
post what I found in my ~/.xmonad directory.

Sorry for the OT, but the famous issue with the ICCCM patch it's on
0.11 or darcs? or it hasn't been applied? For future reference, where
I am supposed to look if I have this kind of doubts?
