I would have made this Excellent if it works as it should.

Contacts are VIEWABLE by every other member without a way to stop this.

Why would user A want other users to see their contacts? It would be nice to CHOOSe to let them be viewable perhaps, but this plugin should be for OWNERs view only, or at least allowed to be that way.

And you cannot use Privacy plugin with this because it produces NO edit tab which means NO way to enable privacy features.

The calendar works beautifully! It lets you choose up entry which events are private or public. Perhaps this should have been done for contacts.
