Good idea but useless

It’s been more than half year since I asked for some enhancement/fix, but nothing happened. The plugin looks good but pretty useless. #1. It does not allow you rotate about horizontal axis, so you can never see the model botton. #2 the rotation event handling is awful. #3 the developer decided not to use parallel perspective, this way the model looks quite deformed when zoom in. I am really hoping they are fixed.
