Notify only once, and not when app is open
Im using the windows client. I either get no notifications of new messages, or I get popups and dings constantly for every message, even when the app is open and Im replying in chat, or when Im talking, which is rather annoying. Ideally I would get 1 popup / ding when a new unread message is sent and only if the app is running in the background or at least the chat window with the person sending me the message is not open, and then no more until I actually read that message.
Also, an indicator of unread messages in the tray icon would be extremely helpful.
