This is, sadly, not in the control of twitch. It is something you would need to take up with the console manufacturer. It most likely works that way so you don't accidentally show the world private info while in the consoles main menu which often shows your real name and sometimes email address, etc...

This would be great to small broadcasters that cant offord good recording software :)

Tons of PS4 and XB1 integrated Streamers complain and feel bad that when they have to switch games, the stream will go offline. This idea would make sure that once a streamer who uses the PS4 and/or the XB1 App to broadcast switches games, it will keep the screen in the "blue shapes" or "green environment" mode of casting UNTIL they go to a different game, where a different game will be streamed OR go to the "Stop Broadcast" button, where it would intentionally end the stream. However, when they switch games, they would have to go to their dashboard and change the title to show what game is being played. This kind of plan supports all starting streamers when they want to switch games so that their stream does not go offline because some people wanna try out marathons yet this disconnection ruins the marathon whatsoever. We need to help streamers overcome this issue.
