There are a few small UI improvements that could really improve user experience. for instance:
- an icon or indication that a variant has a specific price (other than the parent product price)
- the ability to delete/copy existing values when changing a product type to a diferent product definition. At the moment you make the switch, creating all new fields and when you switch back the old values appear again. From an IT standpoint this is logical, but the content editor will get confused by it.
