I can't find this setting, but it would be great if it were possible to disable the chat feature.
Edit: deleting because this is already being discussed elsewhere.
If someone chats you and you haven't viewed it yet, would be cool to have it flash in the title bar in case you're in another tab. Back and forth between Chat from User and the actual title of the page you're on.
Oh wtf this already happens.
Fuck I'm retarded.
Theres no notifications, only shows the lasts chats. but when someone talkto you not appears notification in that menu.
As far as I know, that menu doesn't show unread chats, so that's working as it should.
On mobile theres any menú to see chats
