Allow user to create multiple profiles/identities

As someone that likes to compartmentalize parts of my life for personal and operational security reasons. I would like way to be able to have multiple isolated profiles in an account.

This would enable me to sync just my Work jots/notes/tasks/calendar when I'm at work, and just my Personal ones when I'm at home.

I think the task domains are supposed to in some sense address this issue, but I don't want my work computer to have access to my personal notes, and I don't want my personal computer to have access to my work notes.

I think perhaps I could just create multiple accounts as a work around, but I'm unsure if this would be frowned upon.
