Hello!
Thanks for this project. It is really helpful!
Is it really to hide some built-in groups in menu items but show in Dashboard? (F.e. Auth, the item from celery(Periodic Tasks) etc.)

There is no ability to do this today, but I would gladly accept a PR if somebody wanted to implement this function.
