People who hold several roles, such as a full-time job, a startup and content creation, use the same apps across all of them, but with different accounts, files and conversations for each. Because these apps aren't organized by role, every switch means manually reopening the right setup while the previous role's apps stay open. Those leftover apps keep pulling attention back through notifications and visible tabs, so starting real work in the new role is delayed, and focus is split between two roles at once.
