the right hand menu is the system menu which cannot be overriden in any
scenario. this is needed to always give users the ability to pause/
exit/ recenter their view.any reason not to use the left hand menu for
this (the app menu button)?
the right hand system menu cannot be overriden- it is the system level
mechanism to stop/ pause/ recenter.this is equivalent to the right
controller oculus home button, which cannot be overriden either
