• Page Labels (Pages > Page Labels…, or right-click a thumbnail): name a range of pages with 1, 2, 3, roman numerals, or letters, an optional prefix like "A-", and a starting number, with a preview. Pages outside the range keep their labels, Remove All Labels goes back to plain page numbers, and Undo works like any other page edit
