As an organizational method, it would be nice to have the ability to assign an article to multiple folders. When editing the article and once the article has been moved to a folder, the interface could show both a choose button to move the article again and an add button below the choose button on the page. The add button would allow the article to be assigned to an additional folder, much like how a hard link works in Linux.

Sometimes an article makes sense to be classified in different areas of the Global KB, so it would be helpful to be able to put the same article in multiple locations.
