A Group course has seven tabs, more than 1:1's five (4.3), reflecting that multiple learners share one course: Timeline, Sessions, Content, Landing Page, Leaderboard, Learners, and Settings.

The empty Timeline is a social feed, not just a status page: a "Share something" post composer (plus Share a poll and Attach files), an "Invite learners" card (5.3), a "Schedule sessions" card (5.5), and a "Certificates" card for rewarding learner achievements.
