- A study share link can hide the owner's notes until a chosen time: the server sends only passages and discussion questions until then, with a banner in the shared view (new share_reveal column, migrated on start). - Outline: a session length with "N of M min planned, X min over" and a marker on the point where the plan runs past it. - Export > Slides: printable 16:9 slides (title, passage, outline points with their verse, discussion questions) for one session or all; light or dark.
