hemlockiv Did you hear it's just 2 userspaces?
Yes, it is only two user profiles that can share home screen, and one of them have to be the owner profile.
hemlockiv You can already do that with any Work Profile management app, like Shelter.
Likely, I never tried that. The difference here is that you do not need to install an app that is given deep privileges over your phone. I don't know if Shelter is vetted as trustworthy or secure, it is a third-party application you have to install yourself. But Private Spaces is a natural and secure part of the system, just like separate user profiles.
hemlockiv I thought the point of Private Spaces would be more than 2...
I heard GrapheneOS developers are already considering to extend it to more than 2, but it is not a top priority right now.
