Members grouped by tier — the hierarchy is visible at a glance without being the first thing you see.

"Never joined" section is a first-class view, not a footnote. Knowing Grandma hasn't opened the invite is useful group information.

Activity shown per member — committed items, claims, forks. Participation imbalance is visible without being called out.

Tapping any member opens their profile — where the organizer can change their access tier if needed.
