Better privacy options and friends integration
You should be able to "go offline" so friends can't see what you are playing or send you notifications/party requests.
Also, you should have a standard API to allow you to invite friends into any game and instantly join the action. For example if you're playing Rec Room you should be able to send an invite request to friends and have it auto join the room/game you are playing. If you're playing Pokerstars and send an invite they should join your table not the main game lobby.
Lastly, there should be a global push to talk feature. The headphones are Quest are HORRIBLE for social gaming because the mic pics up game audio and echos it back. Push to talk would be one simple method to reduce the feedback
also I would love to have the chance to send short (maybe standard) textmassages to friends to ask them, before I have to send them a party-invitation and maybe disturbe them while hitting hte highscore..
And for those who sent me an party-invitation while I am playing a game.
Something like "sorry, i am busy but will answer you shortly" or "are you up for a littletalk or multiplayergame?"
Just not answering party invitations seems rude!
