I'd find it quite helpful if you were able to make something private and have some settings where you can only allow certain people to see it or download it ect. Since people may have stuff they've created when they started but then want to delete because they just don't like it anymore, I did that once but I lost a lot of stats like XP and diamonds which set me back a bit and that is frustrating. But with this you can change the settings of who sees it, but without losing stats and stuff.
