Issue description

Under "User groups" > "Edit group" in the "Back end modules" section, it is not possible to select MetaModels under MetaModels. You can only select "Support MetaModels". So no user but the admin can access the MetaModels "Creation Panel".

We should discuss whether the restriction should remain that way or not. In Contao I think you can also unlock everything for a user group...

Not everything but yeah, we can discuss the pro and cons.
It was visible to all in prior versions way back in time and restricting it to a certain group/user wasn't worth the hassle and we came to the conclusion that only admins will manipulate them anyway.
