Hi Michael,
With the current mechanism for controling the surrounding points movement, is there a means to control the radius of the constraint?? So as is now, points at further distances move less down to the non moving part... Can we grow or shrink this "Weight" of the movement?

Also, it seems the "drag" command is located in the Command processor part and not a js file?

Thanks.
