Austin, thanks for the continued insightful feedback.
Our main approach to enable more realistic views is to allow taking pictures of FoV on site. We already support this but it's only via PC, which makes it time-consuming to take it on your phone and then transfer, upload, etc.
Next after indoor mapping is releasing a mobile app which will incorporate taking photos of your FoV (i.e., you are on site, you pull out your phone, open the IPVM calc app, add a camera, take a picture and that will show the real FoV immediately). That's for the end of this year and is our main approach to ensure the most realistic FoV / previews.
As for the other approaches, we are aware of them and are considering them for next year.
