It's a good start! Keep going!
@Keet
I've test it and NO, not this time. Maybe in the future.

While this plugin act as a multiplier what if it will be added as feature to the current Multiplier?
Could be BUT not before to have a more performant (customizable) polyline in the main program.
What's in my mind:
The Art Off Illusion (java) have the option to draw objects (or extrude) along a curved line especially to make pipes.
Could be a good source of inspiration.
