Do the additional fields show on all discussion categories?
This plugin looks very interesting. I read the Readme file and it's unclear to me whether the mention of "Required on all discussions" may be set to be required (or optional) but limited it to specific categories.
What I'd like to do is to use this extension to add fields to a specific category without affecting the other categories. For example, if one category is about a product, to that category I'd like to add a field "Product Version".
