Using a different administration theme according to the role Is there a way to use different administration themes according to the roles assigned to users?
I have two roles (admin, editor), and I want that, when creating content, users with the admin role use the garland theme, while users with the editor role use another theme.
The ThemeKey module lets you set the theme using many different tests. While it doesn't specifically set admin theme in the usual way, it will certainly let you set a theme for a role and a path, achieving the same result. Some more details about this module (from its project page):


  ThemeKey allows you to define simple or sophisticated theme-switching rules which allow automatic selection of a theme depending on current path, taxonomy terms, language, node-type, and many, many other properties. It can also be easily extended to support additional properties exposed by other modules
