It would be useful to have the ability to hide certain category titles from general users. For example allow only certain groups to see certain categories. Currently all users can see all category titles.
Permissions don't go by category. Coppermine core design would have to be changed for that purpose. I doubt that this will be implemented soon.
I think it could be a great solution: categories to have group permissions too.
Any changes from last post?
No. Locking.
