I have the same problem, i think inheritance of the additional fields is a MUST.
Some of us use lengthy additional fields which will require us to spend tons of time adding them to reviewpost.
Definately should be added to next release, it could be a checkbox to make it optional.
Last i have a question, im gonna create a Query to duplicate those fields inside "extrafields" table, and apply the needed changes to "categories ", but which fields are affected inside categories table?
I located one that seems to be needed: numextra, but i have doubts with revextra and ugnoview.
Can you help chuck?
