Hello, let me start by stating that I have been using, and loving, grid for a VERY long time. I can find little wrong with it.
I do have a question that can hopefully be answered.
Would it be possible to populate grid with people not inside of your group? A perfect instance would be Wintergrasp, when there are 2 raid groups present. I understand that this might be a memory intensive module, and that it has the capacity to get out of hand. My idea to counter that is to only populate grid with people that are say, flagged for PvP, or in combat.
