I'm grateful for this thread because I didn't know this script existed. Thanks!

One thought: It would be dandy if "Nudge" knew the angle of the current view and adjusted what left, right, up, and down mean.

eg: If you're looking from the front, up/down map to z-axis movement.
eg: If you're looking from the left, left/right map to y-axis movement.
eg: If you're looking from the back, left/right movement is reversed.

This can work for diagonal views as well by simply figuring out which cardinal axis the view is closest to and modifying direction and polarity of nudging as if the view was directly on that axis.

It would also be great if the default nudge amount was not "1.0" but instead the current grid snap value.

Is this easy to do? ie: Can an iOS programmer with no JS or MOI programming experience figure this out? If so, let me know:
the JS api that gets the current view angle
the JS api that gets the current grid snap value
and I'll do it!
