When i run a team.. i normally only have the viewers on my main ( tank normally ) with a source for each alt. Now that i have a few teams of all the same class I would like to have the same layout no matter what toon I'm on. So a few questions....

1. If i have the exact same set up on each slot ( 4 viewer windows ) does that eat up a lot of resources? If so...
2. Is there a way to have the viewers only show on the active window? But when i swap to another toon, the viewers on that window become active and the others shut off?
