A simple checkbox to lock the movement, rotation and scale flags of the camera to prevent accidental nudging with mouse. Very easily done when working fast or when using something like a spacemouse.
You can drag and drop two small macro scripts to the viewport and create "lock" "unlock" buttons not only for the cameras, but for any object in 3ds Max.
