Nice way to set things up but did you ever think of this. You know how your f8-f12 buttons are bags right. Well using keyclone maximizer set those f buttons to each window. Then keybind it to say your right action bar. On each toon do the same thing make each button: for example, F8 on each will say. /target 'mains name' /assist focus then on f9 make it /target ' slave1' /assist focus. Do this for f8-f12 on each toon. What this does say your main dies on f8 screen, you hit f9 twice you switch to that screen he becomes main and all chars follow him and attack what he attacks. This has saved me alot and also on dueling. People will want to duel you on each char so they start the duel i hit say f9 twice and i can control that character like it was my main. Just dont forget to have a override for dnp so you can still move them with the wsad buttons and not move the others.
I hope this helps out a little bit
