Unlisted Folders listing child folders, etc

I would like to suggest that Unlisted Folders be allowed to have "listed" (Public) children.

I basically find unlisted folders to be a non-feature as nothing in them ever shows, but if they did it would be a great way to keep groups of things (folders/galleries/pages) hidden behind a link. I've tried sharegroups and events (a long time ago, so forgive me for not being specific) and they didn't work nearly as well as I was hoping, as they target individual galleries rather than the hierarchy natively available in the new Organizer.

Thanks for your consideration,

Andy
