I want some user roles (e.g., admins) to have access to some editor functions (e.g., html or some buttons) that other user roles (e.g., content authors) would not have access to. Sometimes it is important to maintain these limitations for junior-level users in order to preserve look-and-feel continuity or to safeguard accessibility. Can I permit an Administrator user group to the advanced toolbar set and a Content Author user group to a custom toolbar set?
