It is a great addition with tons of possibilities.
One suggestion though: The default settings produce the least desireable result. Defaults should be:
Divisions 0
Spineshape straight (less clutter)
Pairing edge count (this gives the most oredictable result because you know your edgecount but not the relative edge length)
Inerpolation linear (less clutter)


From there you can start refining.

Edit: added screen shot. Left side is default values.
