 * To be honest I’m not sure if it will be useful to me yet.. The site I’m currently
   working on has multiple variations for each product, so customers need to be 
   able to choose the options before adding to the cart.
 * I can see it might be useful for simple product store items…
 * There also doesn’t seem to be any kind of real documentation or a demo of how
   to use it. I know you only just released it, but I think it would help people
   a lot if there was a bit more information and documentation + a demo to see some
   examples of how it can be used.
