Make it More streamer friendly?
I think adding a separate window connected to the stream would be beneficial so that OBS software can detect the window more easily and you don't have to jump through so many hoops. Also, I think a way to create better tracking and even add an option for the puppets could be exported much like Live2D can export theirs, would be beneficial. Being able to add your already rigged puppet to a different non-adobe software would be great for streamers looking to become VTubers. Personally, I find the streaming to be clunky and not well thought out, if it ran more like Facerig so it'd be an easier experience I'd try to learn the program more though.

You can send the contents of the stage panel directly to OBS with an alpha channel (per-pixel transparency for easy compositing) by using the built-in Syphon option (mac only) or the NDI plug-in from NewTek (mac & win).
