Often we need to copy barcodes for demos or when testing, but coyping the link is hard and not always works well. It would be nice if we offered an option to copy the barcode to the clipboard, maybe using a little icon or similar that could be added later in other places as well.
A Swedish library has documented how they add this (and a couple of other buttons) via IntranetUserJS: https://koha.se/wiki/Bibliotek_Mellansj%C3%B6s_IntranetUserJS#Katalog_.2F_Knappar

This is a neat idea. There are also other parts of Koha like the label creator and batch item modification that ask you to paste in barcodes, so I could see this feature being used to make it easier to do those things too potentially.
