Good UI for 4 boxing?
 

I recently created 3 other accounts and i'm going to 4 box a druid, shaman, shadowknight, and cleric. (2 computers)

I'm looking for a UI that is very simple and something where I can put all the boxes and windows in the top rather than the bottom so I can leave it half-screened and still be able to see chat. Very clean and 800/600 resolution.

thanks
