(this is not a big or urgent wish, but I think many of those fine tunings make a great program)
if a single vertex is selected, the default location of the gumball is the point itself.
But why are the rotation handles / 1/4 Arcs shown.
Rotating does not have any effect if a point is rotated around itself.
(as soon as gumball is relocated, of the CV/Vertex Coordinate, rotation might be useful)
