Option to remove the stack item when a user that was in your HO has now left it.

He has entered your HO and now has left it, option to remove the stack item when he leaves your HO. I saw that there is one option to remove on group leave which is good.

a) you left your ho first aka went back to mapping asap - still have to manually dismiss
b) the guy decided he really likes your ho to live here from now on - still have to manually dismiss
c) he left before the trade happened (dced or whatever) - have to pull the notification back from history

It's definitely not a difficult thing to implement but its unreliability bothers me.

If some of the edge cases fail you can go back to standard behavior since a lot of cases the normal case is what is going to happen.
