The Drupal 5 version gives you the possibility to use the administration theme when editing posts. This feature was introduced in Drupal 6 core and is with this module now available in Drupal 5.
Use the administration theme on more pages then possible with Drupal 5 or Drupal 6 core. You can allow the theme on a predefined set of pages and on a custom set of pages. The inverse is also possible: specifying a set of custom pages on which you don't want to use the theme. An example of this might be that you want to use the administration theme (all pages having a path starting with "admin" (admin/*)) but not on "admin/content/node".
Hooks! All modules can now add some pages to the administration theme settings page using the hook_admin_theme hook. By doing so you give inexperienced users the possibility to just tick a checkbox to use the administration theme.
A permission is introduced to allow or disallow certain users to use the administration theme.
