SP2 Admin Center Category mngmt: there isn't the AJAX auto-fulfill option in the Admin Center in order to more rapidly retrieve a category

The auto-fullfill option in order to more easily manage and retrieve categories (such as in the file field on on webdav for files) are not present in the administration center in order to manage categories. This is quite stupid as this is the place usually where the user manage, create, etc... categories. So it would be great to have a tools in order to rapidly find a category value or key and to automatically expand the category sitemap accordingly.
