[ENHANCEMENT] Allow to open links in QR-Codes in browser or copy content to clipboard

[HansS7]

I imported (except others) also some PDFs just for later reading. They contain QR-Codes with links to additional information, but although a newly rendered QR-Code is displayed I did not find any option to use it. I know that this App is (or was?) intended to present such codes from Covid-Certificates, Tickets etc. for e.g. security checks, but general usage of QR-Codes would make your nice App even more useful.
