Administration theme location

Why are the "Administration Theme" settings are located in "Administer -> Site Configuration" area, rather than with all of the other theme settings in "Administer -> Site Building -> Themes".

The only unique configuration option that is in the "Administration Theme" menu is the "Use admin. theme for content editing" checkbox -- and this could simply be moved to the bottom of the list of themes in the "Administer -> Site Building -> Themes" menu. It seems unnecessary for this single option to have it's own section in the administration menu.

As far as choosing the admin theme, why not just add another radio button field in the "Themes" menu, next to "Default" called "Administration Theme", and only present this option to users with appropriate permissions?

The location was not intuitive to me. When I began using Drupal -- my first guess at where to set the theme for the admin area, was ... well ... in the themes menu. Of course, I could have noticed, if I had scrolled down a bit, that there was an option called "Administration theme" -- which is obviously what I wanted -- but the section called "Themes" caught my eye first, and is at the top of the page. It's not much, but it would have saved me the minute or so I wasted digging around in the "Themes" menu.

This would also have the benefit of reducing the clutter in the "Administer" menu a bit, making it more easy to navigate for new users. Another benefit would be that if I wanted to change both the admin theme and the site wide default theme, I could do it in one place.

Is there a reason that it is currently implemented this way? Just wanted to hear other people's opinions on this, and figure out if anyone knows why this needs to be separate from the rest of the theme options?

Thanks,
