The spout stream is excellent, thank you!
Because this detaches the game window, it makes it easier to stream games where you might want to do two captures - the gameplay and the streamer avatar.
I love that, but I have viewers that are prone to motion sickness.
I think a fantastic addition would be adding spout streams per pin, with an over-arching spout stream that is whatever the current pin is set to.
e.g. VRChatCam would be the current camera pin
VRChatCam1 would be pin 1
VRChatCam2 would be pin 2
This would let me setup a camera to record gameplay as well as a camera to record myself, and would be a smoother camera experience than POV where any head movement shifts the camera.
I also think leaving a view as whatever the currently selected pin is is important for creators who are live streaming and want to change the camera while streaming (most Just Chatting or Talk Show streamers)
