This looks really well made. I also enjoyed looking through your other (very clean) repos!

One question: does this work with React? I found this Github https://github.com/kwnccc/react-popmotion but it isn't part of the main Popmotion organization. I would be willing to pay a license fee for something well maintained with React support.

FYI, The pay structure I agree with most for web libraries is a non-recurring fee, 1 year upgrades and support, the versions I purchased are useable indefinitely but I can buy a new 1 year license for the newer versions and more support. Up to you how you do it though!

Fundamentally, it works with every API you can stuff a number into. "Number" includes stuff like hex/rgb values and complex strings, too.

So yeah, it does work with React, however:

1) It will only do CSS value detection (stuff like prefixed values and transform value mapping) if you either give Popmotion a direct reference to the underlying DOM element as if you were using it normally, or manually set a CSS role on Actor init. This only becomes a problem when you're working with completely stateless components, but then it could be argued that stateless components shouldn't be responsible for their own transitions. This is because:

2) No JSX support. I've seen the Velocity React implementation and I'm not convinced this is the best API (if you haven't seen it, check it out: https://github.com/twitter-fabric/velocity-react) I wonder if the drive towards JSX-everything isn't a misstep and that in some situations things that should be `params` are being made into JSX tags.

I don't have a wild amount of experience with React so I'd be interested in hearing your thoughts.

And thanks for your opinion on the pay structure, I think we're largely in agreement there. Good food for thought.
