Hi Andy,

re:
> OK, so why is point selection not used here? Andy

Because the main thing it's looking for is an object and the object picker is best at selecting objects.

Probably what it should do is show a point on closed curves that you could drag in the options stage of the command to change the start location. For now though with a circle the start location can be easily changed by rotating either the circle or the result of the flow around the circle's center point.
