I was going to post this up in bugs but wasn't sure if it was just me
I take it you mean the red circle with players in it that when you move the mouse over gives you the first 3 players and a "more players" message but you can not click on the more players part ?
I agree as well. I would like to see everyone who is in the town and visiting. It would make it less of a shock when you check your reports and find out someone dueled you and you never knew they were in your town.
