This would essentially just refresh the webpage but multiple users have requested the desire for a 'home' button to reset from where they have navigated into the scene.

Thanks, yes we definitely want this as well. The challenge right now is where we would fit it into the UI that wouldn't make things more busy than it already is. We are working on a UI/UX evaluation to come up with a solution for this.
