[xmonad] withIM combination

[Alessandro Massignan]

Hi all,

few months ago i give xmonad a chance and I really like it a lot...
There's only one problem: i'm an ultra-rookie to xmonad and to haskell, so
i beg for knowledge :-P
I try to setup a layout suitable for chatting and looking around I found:

* XMonad.Layout.IM
* XMonad.Layout.LayoutCombinators

what I'm trying to do is to set up a layout that split my screen horizontally
in two sections and LayoutCombinators seems to be the one; each
section is handled with IM layout.
I've forgotten to mention that in the upper section i run pidgin and in the
lower skype, so in each section i want the buddies list on the left and each
opened chat to be "tabbed" on the right.
Basically i have this:

tabbedLayout = (tabbed shrinkText tabbedTheme)
commLayout = avoidStruts $
             (withIM (0.20) pidginRoster tabbedLayout)
             *//*
             (withIM (0.20) skypeRoster tabbedLayout)
pidginRoster = (ClassName "Pidgin") `And`
              (Role "buddy_list")
skypeRoster  = (ClassName "Skype") `And`
               (Not (Title "Options")) `And`
               (Not (Role "Chats"))    `And`
               (Not (Role "CallWindowForm"))

ok, it runs but with an essential issue: every chat window is tabbed in the
upper section, while i want the pidgin chats above and skype chats below.
Any hints?

Thanks a lot! :-)
