Ermergurd, Flob. That'd be awesome, that way you wouldn't really need to add people in your group to find them. When you're an organised person like me then you just can't be bothered to add all your group members to have to find em' xD. Plus one might not want a spammed buddy list just because they need to find their group members. And if they get lost then it's easier. I'd like to add on to your idea with adding a different colour dot for the owner of the group shown on other people's screen, that way it would be easier to find the group leader. If I made it clear enough xD
Awesome idea! :3
