I am looking into how I might customize the backend, but re-themed is not the ultimate agenda. Say for instance, 'admin/content', where I have filter options for various content types. Below that I have a table of content sections.
I want to completely replace the table and render the list in the left region of my template and use the content area for a WYSIWYG editor -- this is a common UI for basic CMS and I figured would be a good advanced learning experience.
I started poking through the code and quickly discovered I have no idea what content/form/blocks are in which regions in the admin section.
I found the module that implements the menu for 'admin/content' but that wasn't very helpful.
My question is: In the admin portion of a drupal setup how would I position custom block module content in the right region of a template when using block admin seems only to affect the front-end of the site?
