How does the studio screen work?

The left column holds the cards: Print check, The book, The designs, Color by number, Pages, and Cover and listing text. The middle shows the real page, exactly as it prints (numbers and key included), with arrows and a page list to move through the book, and a toolbar for the page shown. The right column, "Designs", shows every page as a small colored picture (the answer), with the "Photo page" button. The top bar reads "Activity Studio · Color by Number" and shows the title, the number of designs and pages, the trim and whether the book is saved, with "New designs" and "Export". The arrow at the top left goes back to Activity Studio.
