I would like to see a better movement imput system, like the rotation gadget 3dmax has or the 3 buttons MODO 302,401 has for rotating, translating and zooming the camera. Also if the editors do have the 4 views system it would of been nice if they could be locked to a specific view i.e: top left front and perspective and be able to resize them.

The only good navigation mode right now is in single view with zoom in full (1st'P) and with WASD. Which is fine for world placement but cumbersome for model editor, or precise movement.
