I am looking for a 6-man group window. I have tried my hand at editing some of the 5-man windows that I like, but I don't know a lot about XML code and thus far, have been unsuccessful at what I am trying to do. I am wanting to add myself to the group window, but in such a way that if I am not in a group at all, the window is empty. The 6-man windows I have seen so far show the player alone at all times, even when not grouped. Is there a way to do this? Thanks!

P.S. I understand a little bit about XML, so I'm really just looking for that specific bit of code required to make this happen, if it is even possible.
