How does the studio screen work?

The left column holds the cards: Ready to publish, The book, The mazes, Pages and solutions, and Cover and listing text. The middle shows the real page, exactly as it prints, with arrows and a page list to move through the book. The right column, "Mazes", lists every maze by level, in the order they print. The difficulty curve is at the bottom. The top bar reads "Activity Studio · Mazes" and shows the title, the number of mazes and pages, the trim and whether the book is saved, with "New mazes" and "Export". The arrow at the top left goes back to Activity Studio.
