Simpler Product Classes

A particular annoyance I've had with ubercart is that each product class needs to be created in the Ubercart admin pages. In turn, it generates a NEW content type.

Instead, I'd rather be able to create whatever content types I wish, and simply apply a flag/attribute or what-have-you to content types I already have.

If you need to see an example of my proposal, setup a D6 instance, and download the "Classroom" module. under the admin side, see the "Course" settings. You can check off which content types are "courses" and which are not.

It may be even better if content types could be managed in a hierarchy -- but that's entirely up to the D7 core.
