Limited read access for selected users

[frawi]

I want to share my calendar with other people, but only show them when I am busy. Right now I can share the calendar, but everyone gets the same access the events. I can decide for each event whether it is public, private or confidential.

I want to share my calendar with some people (business contacts) only to show them when I am not available/busy. I don't want to expose more private information to them. But with other people (family) I want the standard sharing where I only hide some selected events.

This should be configurable for both users and sharing via link.
