outline desginer

I've been working on a project to make the structuring of content easier / more intuitive. The module was called the Outline Designer and now there's a Drupal 6 version out now. Please check out the demo below and let me know what you think. It implements a bunch of usability things I've been seeing thrown around on here as well as introduces some new concepts (like a context menu). It integrates / overrides the admin/content/book interface to add ajax elements such as deletion, add a child, content editing, and renaming.

The outline designer has been posted to drupal.org ( http://drupal.org/project/outline_designer ).

This is the first module in an installation profile which will be ELMS - e-Learning Management System. More information about the ELMS project see the ELMS attack plan posted on the e-Learning Institute's projects site.

I'm currently working on a project called "outline designer" for release into the Drupal community (5.x branch, out in the next few days as I'm cleaning up the initial release as we speak). What the outline designer does currently:
*Structure nodes in a book visually via drag and drop
*Right click to create, edit, delete, rename, duplicate any node of any allowed type
*Right click to change content type
*Everything is Ajax saved using standardized Drupal node_save architecture
*Ability to enable / disable the ability to create different content types
