It would be good if there was a property what you see is what you get (WYSIWYG) editor for designing KB Articles.

The knowledge base system is very helpful. It should have subcategories (as subnav elements) in the "knowledge base" left nav element in the admin interface.

Each knowledge base article has a category, but it can only be seen in "edit" mode. Please indicate an article's category when it's in preview mode (in the right pane of the admin panel).
Please add this category information to the header when it's being previewed in the admin panel.

Please make it possible to import data into the knowledge base.

Please make it possible to export knowledge base articles. It would be a fools errand to spend hours upon hours entering them only to have them lost by accident or if you leave the service for some reason in the future. I have hundreds to move from our own FAQ system.

It'd be great if I could re-arrange the order of the articles in the Knowledge Base including by date and alphabetical order

It'd be great if I could change the order of the articles in Knowledge Base by alphabetical and date order.

We'd love to be able to attach pdfs to articles in the Knowledge Base.
