Working as technical illustrator there are alot of occasions where you have to use cameras in orthographic mode (or) just a orthographic viewport. 3dsMax does handle Isometric Views quite well. So 2D pannig would be very welcomed here too (and the possibility to create a ortho camera from view as well, by the way).
This applies to Direct Light View, Orthographic Viewport and Camera with "Orthographic Projection" enabled, did i forget something?
I really can not imagine why some one would restrict this useful feature to point perspectives.
