This is a feature request to extend the permissions system to allow more easily other local acl options.

For example auth_admin::acl_set could be modified to take input like

function acl_set($ug_type, $local_id, $local_option = 'forum_id', $ug_id, $auth, $role_id = 0, $clear_prefetch = true)

Obviously FAR more to it then just that lots of functions like get_mask, get_role_mask, display_mask. Some functions would need to have the option $local_table etc.. as well and its not a small change, but thought early in the process is the time to submit such a request.

It would make the permissions system even more flexible.
