Glad to have you in the group. This suggestion just came up in the office hours meeting in VR on Friday! It is definitely something we will consider down the road, however, we want to focus on making things load faster, so that a progress bar isn't necessarily a must. Thanks for your patience in the meantime - the good news is once a scene/experience is loaded and cached, it should fire up much quicker the next visit.
Hope to see you in office hours one of these days!
If you can speed up the speed of entry that is really the best solution, and look forward to refueling.
