Agree with above. Manufacturers are a primary entity and should have an admin interface.
In related news, the columns when i finally found the attribute-editing interface were incomprehensible:
Default Store View
I have just now installed magento and am trying to add a couple products to see what happens. I have no idea what these mean. “Admin” apparently means “Name of the Manufacturer” because I guessed and put “Sony” and that seemed to work.
If you have a default promotion (20% off Sony products) why not have that manufacturer in the data fixture?
PS: Sony is evil. Please change to Nintendo
Cool software, guys, keep up the great work.
