Many Players use !closeall & !openall because they think their game will move up in the Lobby list. I dont know if this is true but i think many of the double-click and cant join Problems are caused because of this. For example there is a lobby in your list and you double click it and arent able to join. Now refreh the list and search for the lobby and now you can join. Its a verry anoying Problem created by the hosts i think.
I agree. They should just have a better way to deal with this if it still works. I wonder what sorting by Oldest first would do. Probably need more filters if that was the case.
