Scan a position does more: paste a FEN you copied straight from the Puzzle tab, and copy the FEN of any position you scanned or set up, to share or use elsewhere. On Mac, pick screenshots from any folder, like Downloads or the Desktop, and Paste is back. The scanner reads tightly cropped diagrams more reliably.
