I am trying to adapt it to act as a content manager suited for my needs. It's not anywhere near to be completed but we're going to implement it soon on our site. I'll update you once I have something to show.
Since this is not a project for public release I'm not developing a very robust interface where you can drag and drop widgets. I plan to have several templates though for news, articles, multi page articles, etc... You specify the type of article you're creating and the system changes the template accordingly.
