Add Preview to draft page to see how unpublished content will look once published

We really need the ability to preview our pieces of content (KB, conversations, etc.) within the Article draft area of Control. We of course can move a 'live' article to a private sub category to preview it and then push it to the LIVE sub category later but, this involves a few extra steps and is a bit cumbersome.

Adding a preview button within the article editor would be ideal.

Thanks!
