Is it possible to position windows on the floor by changing some setting? Currently, they cannot be placed on the floor due to drag limitations.
Re: "The dragging angle limit seems somewhat arbitrary anyways — like the developers had to go through extra effort just to restrict the movement of the windows to within specific angles around head. Why?"
Try ask about this is the Design topic area.
The design guidelines for visionOS can also help disambiguate certain design choices.
Otherwise glad to hear that you're aware of the currently available approaches.
Again, consider an Enhancement Request.
