I notice on high pop zones like Bajor, ESD, or First City if you're trying to meet up with a team mate or friend, you don't always see that instance on the list. I figured if that person was in a full zone it won't pop up. However it seems there's no order to the list at all. perhaps a sorting option would be helpful. It has taken perhaps six tries hopping zones to get the friend's instance to come on list, then it shoes it's half full. I'm not sure if this has been addressed before.
