A few things I would like to see in the CMS* that do not appear contemplated from the screen captures:
Subheadings: I would like to see the ability to tag specific subheadings in an article* with consistent formatting across articles* rather than using the formatting tools (bold* underline* italic* etc.) to independently format any given article's subheadings.
Section Editing: Once you save an article with defined subheadings* I would like to be able to edit (or delete) each subheading and its associated text* independently of editing the entire article. (This is akin to present functionality - being able to edit a specific post within a thread). Similarly* it should be possible to insert a new subsection before/after any given subheading.
Table of Contents: The option of automatically creating a table of contents for articles with subheadings* with anchor links to each subheading.
