It would be useful if there was a feature that would allow us to create an article as a replica of an existing article, which updates when the existing article is updated. So basically linked articles.
A quick way to have articles appear under 2 or more categories without duplicating them. For example, under top category FAQ, a subcategory for Sales, and the same subcategory of FAQ (with numerous articles) under top level category Sales. All duplicate articles would be automatically updates when I update 1 article.
