I'd like to create a page in the WP Admin backend that is just "white", e.g. without the administration menu or the admin bar.
I am NOT looking to create an admin page without adding it to the menu; I'd like to create a page in the admin, where it is simply "white".
I need this because I need to run an import script, and it needs to load as fast as possible. The user would not need to use the admin/adminbar, and it would just slow the process down.
