Big win over the last 24 hours! Barcode scanning now supports older/80s books (which use UPCs, not ISBNs). I haven’t found a book on the shelf I couldn’t reliably scan yet. Way better than the v1 app which really only supported newer books properly.
To make things even easier, there’s now a dialog which prompts you on how to scan older books (you must capture both barcodes!) vs newer books.
