I find quest Very limited in terms of personalisation. Probably its limited by the memory. I am mostly talking about home environments. Although we have VR, the home experience is very 2D.
Imagine you can map your room, apartment or a house like in your app, include furniture or other objects you can download or create yourself in CAD, instead of menu you have a portal/doorway to the installed game, TV mapped with Netflix or similar app, e.g. google maps projected on your table(like in that awkward home mapping solution), which displays location of your friends with their VR homes you can visit and play some simple games.
Anyway, the direction is very good and i will certainly enjoy your creation.
Keep up the good work you do!
