I am trying to configure 3 clients with whichever has focus in a main area 1920 X 1200 and 3 640 X 400 pip window on the right side. Basically I want to always see client 1 at the top on the right side, client 2 in the middle on the right side and client 3 at the bottom on the right side. I don't want an empty slot where the active client was when it goes to the 1920 X 1200 window.

How would I modify the Multi script to achieve that?
