document.execCommand('copy')

WHAT! https://developer.mozilla.org/en-US/docs/Web/API/document/execCommand

what's designMode. This is awesome @Kieran, this functionality has been on my wishlist for a long time xxx

With the accordian, sure I get the QR code over the shoulder thing. Perhaps make it so when you open one it closes the others? I think the kicker for me is clicking to open one then scroll as well because the QR code pushs the next ones off the window. Yes I am that lazy / irritable !

I think printing QR codes is an interesting case i'd not thought of. I reckon if that's the main use of them, then it should be designed for - like an A4 page with all the QR codes tiled that you can print off and cut up. That would actually be super fun to send them through the mail or something.
