3d view model upload retry is too long. When not all 3d models is succeed loaded in 3d view mode - next load try is making after pause about 30 second. Then all 3d view loading can need 1-2 minutes. It's too long. Previously, this pause was very small and almost imperceptible, but now it spoils the process. Plus make shorter pause. I think about 5 sec is ok.
Brand new interactions and interfaces. 
Easy to use and quick to get started.
