I think it would be awesome if WordPress allowed multiple post pages controlled by categories. In other words, if I could create a page and assign a category to it, allowing me to post various articles to different pages. Sub-categories could be used to organize articles within pages. It would greatly improve content management if this were native in WP and not solved by theme. I've seen some attempts at it through themes, but the limitation is that there's still a page where everything gets posted. I'd like to determine what gets posted where.
