Copy pasta from the Users page in HA 
I think it would be nice to have user levels.
An example:
Superuser/admin - me doing all the HA configuration and setup, adding stuff etc
Regular user - Access to (all/some of) the dashboards, cannot change any configuration --> my girlfriend who uses HA on her phone most of the time, she can interact with the dashboard but should not be able to accidently change configuration
Restricted user - e.g. for kids, can only access or do actions you specifically allow like turning on/off lights in their room, but cannot open the garage door (perhaps not needed and also possible with regular user?)
How much of this is already implemented / on the roadmap? I know there is a regular user level already.
