OG mandatory group settings needs scrolling list of all groups

The og mandatory group settings box only shows options for "none" and six of the groups on the site. Fortunately the group I needed to set as mandatory was at the top so I was able to go ahead and use it. But, a scrolling selection box would be nice.

On registration the group name is displayed and checked but grayed out. Great.

I was also wondering about trying http://drupal.org/project/og_multiple_mandatory_groups_by_role but it has not been updated recently and did not appear to work for me.

Thanks,

Izzy
