As a user and artist thats using 3d software will say: change the check box ortho to a list(Perspective / Ortho). Change “Other” from the list to “Perspective” or “user Perspective” or “user view” something like that from a user point of view.
When in perspective = list(other) You could do your free actions(rotate, pan, zoom) and when you go to top or etc, also free action, but a user will use more pan and zoom.
Ortho mode = other, should allow for rotate, pan, zoom in ortho mode, but when you go to (top, right views, etc…) you should lock them and only allow for pan and zoom, focus on selection.
That should bring better user interaction.
