In thinking of a groups implementation for a corporate intranet, Hierarchy and Organizer are great plugins, but there is no way to enforce any type of layout structure on the Groups page on the front end.
It would be great if there was an option on the back end to Lock in group order
This would do two things: Always display the Groups list on the front end in the order established by Groups Organizer and remove the dropdown filter on the front end to prevent confusion in ordering the groups.
This is something that should be an option, or perhaps a coding fix like you write on your blog to extend these plugins. The two plugins work so well together, but the Organizer is limited since it only helps build hierarchy and has little effect on enforcing display. A feature like this would give Organizer control similar to the way the WordPress Menus feature works in organizing menu items.
