Maybe a bug: I selected "Generate" and didn't notice that the QR code had been generated as it was off-screen. So I re-selected "Generate" a few times before I realised what was happening. Only, now I have two long columns of QR codes.

This was on Firefox Nightly on Windows 11.

Thank you for the feedback! I’ll try to see what I can do about it. Perhaps make the QR codes display in a modal in front of the original content. Alternatively, I can try having the page automatically scroll (with ease-in and ease-out) to the QR codes.

Actually the QR codes should be replaced if you click "Generate" multiple times. I guess that also needs to be fixed.

This has been fixed. After every click of the "Generate" button: 1. any existing QR codes are replaced; 2. the new QR codes scroll into view automatically.
