+1 There’s no reason that my babysitter using the tablet, needs to be able to see where the wife and I are or any number of other things that aren’t explicitly set as available to that user.
Even if someone can make API calls etc. and that changing that would be hard to implement. Non-admins do not need to see these items on the side bar. Other sidebar items are currently able to be be shown or not to non-admins.
