• you can select an entire Loop of points.
  • you can advance to the NEXT/PREVIOUS Loop of points.
  • if you had a selected set of points that were all members of the same loop (but a subset),
  • it should be possible to advance to the NEXT/PREVIOUS equivalent points in the next/last loop.

This would be convenient if you were working on features that follow a contour, but are at right angles to the Loop polyflow.
