Well, it's not a wonder app, just different. You need a morphed and unmorphed figure in the same scene, both with the same garment, and the quality of the morph will decide how the calculated morph looks. It has a lot of potential, but it's still not a miracle. The main advantage is that it works from posed figures to posed figures, which the other tools I know cannot do.

For a high quality morph transfer, which I plan to use over and over again, I would still bring the new morph into Silo and clean it up a little bit. I like PML because I don't have to save a new figure with a custom based morph just for one transfer. But if I create a new character morph and want to give it a big bundle of clothes, I would use Morphing Clothes batch transfer, because that is much, much quicker than transforming each garment with PML. I both cases, I need a modeling app for a final touchup, and for that I need the Morph Loader from PML. 

It's a great new tool with new possibilities and new limitations. I'm pretty satisfied in was it does now, but it's still not an one-click solution with perfect results.
