Cast and save 360 panorams. So it would be much better to watch tutorials, previews and creations. Also store can have vr images, so it will look more cool.

+1! Also video recording would be best if it's steroscopic so it can be shared on youtube as 3D video

The option for screenshots as 3D 360º panoramas would be amazing. Not to mention it would be great for promoting new games to Quest users—they would be immersive, engaging previews!
