What is "A page for each level"?

Before each level's puzzles, a title page with the level's stars, its name (for example "Hard Puzzles"), the range ("Puzzles 81 to 120") and a sentence on what the level asks of the solver. You can give each level your own name in the boxes under the option (for example "Morning Warm-Up"); the level's real name is then shown next to the range. With this option on, two levels never share a puzzle page.
