It would be awesome if it's possible to customize your Playstation4-stream in Twitch Studio.
Maybe you can use the stream code to Synchronize playstation4 and Twitch Studio Beta. So we can have different layers in our stream without buying a third party device such as a Elgato HD60.
I would love this to be possible on my Xbox. I actually got to this page while trying to find out if Twitch could possibly be working on enabling console streamers to do this. I do not want to invest in a capture card only to find out later that Twitch will enable this.
