Adding more fields could be something in this though. I see one problem..should such fields be global? ...or per-article-based?
Oophs.. I'm lost. Would "if it's empty, don't show it" work?
I don't know how others would use it, but I would actually prefer to set it within a category. The "same type" of articles probably uses the "same type" of fields. Just like the way we set post icons in SMF to specific boards when those icons don't fit other boards. But that doesn't flow with how things work now since we don't choose a category before writing.
