Hey,

yes, a new control mode using scaling for forward/backward motion
including the normal rotations
as in the "normal mode" would be very nice. Especially for navigating
through very large systems
this can be most helpful, since moving the camera creates these depth
cue issues.

Best regards,
Christian
