Is it really necessary to count 'joined/left' messages in the unread number on the chat window? I think it would be better if only real messages were counted towards the total. I don't really care that people are leaving and joining a chat when I have it backgrounded, but it's useful to see new messages as soon as possible in, say, the New Streets group. Please can we have either a dual count of total/real messages, or just count the real ones?
