fast forwarding through an experience

There’s something to be said for forcing people to go through an entire cinematic VR experience without the option of fast forwarding, or backtracking if they want to get a closer look, however Within has a pretty good navigation bar and I’m wondering how easy something like that would be to implement? We’re working on a number of immersive music videos and a short film, and it would be great to tie them together with a common mechanism for this. Maybe someone has already shared one that others can customize?
