Schema suggestions — Suggestions where the work is
You do not have to go back to the map to act on a review. Once one has run, any table with something outstanding carries a quiet ✦ Suggestion button on its toolbar — on the grid, and on the calendar, timeline, tree and map views too. Open it and you get the same card, with Apply in place.
It appears only when there is something to say about that table, and only for admins. No review, or nothing outstanding, and there is no button.
