Perspective view, and compatibility with 3D mice - preferrably 3Dconnexion's

It’d be great if there was a perspective projection view available - the current flat projection distorts parts and makes it harder judging the orientation of more complex parts.

Also - 3D mouse support would be brilliant. Manipulating objects in 3D is just so so much better with the right tool. I started using the 3Dconnexion space pilot a few years ago, and switching back to a normal mouse is such a drag.
