Multiplayer notifications in skirmish

It often happens that I don't get to find an MP game and I don't want to spectate either. Ideally I would go into skirmish and get notified when the game I'm in (or I've selected to monitor) is about to start, end, or a new player joins, or if MM is available. That way I won't appear AFK and the potentially joining player doesn't loose interest immediately.

Please tell me if there is already a method to achieve this, or if it'd have to be implemented first

in the lobby settings, under Lobby the last tick box is 'Stay in MM queues on launch' which means starting a game does not cancel your mm queue. That's probably like 7.5% of what you want to know, but it's all I know.
