Would be really nice to be able to sort the in game party list by server, min level, amount of people. 

Also would be nice to see who is in the party before you join. I keep seeing partys that say they are for 30+ but its full of 15-25

Make party members name in a different color or little bit larger text so it can be eaiser to spot in a crowd of people.

Also when I try to leave the party it says you are not the party leader.
