I've been working lots with categories lately, what with the increased awareness and demand for themed or silo'd site structures.

To that end, I'm looking to enhance my category landing pages by relabeling the "Description" field as "Summary Description" and adding a new field called "Detailed Description".

I will be using the "Summary Description" field on my category index page (a listing of all my site's categories) and I want to use this new "Detailed Description" field to show on the landing page for each category.

So I need a rich text edit field added to the Category Edit Screen.

Does WordPress make it easy to create an instance of a rich text edit field, perhaps pulling a light version of the post/page editor? I probably don't need a toolbar, but it might be nice to have some basic formatting buttons like B, I, U, hyperlink, etc...
