Restrict this plugin to admin only

Duh… answering my own(stupid in this case) question.

We gave our editors the edit_users and create_users capability ?? and therefore they got also the capability to use this plugin. Which is our problem and NOT the responsibility of the plugin!
We will have to make ourselfs a function to prevent them making use of this (imho great) plugin.

You could do something like this:

function my_restrict_author_slug_editing_to_admins() {
    return is_super_admin();
}
add_filter( 'ba_eas_can_edit_author_slug', 'my_restrict_author_slug_editing_to_admins' );
