The Share button menu item that produces a QR code for the current page URL is very nice, but would be even nicer if the QR Code was capturable for use elsewhere.
I suggest putting .png file content in the system clip-board.
If this is hard to do, make the popup QR code clickable or right-clickable, and result in a save-file dialog, offering a name like https—orionfeedback-org.png .
This allows users to easily embed QR codes in other documents
The precise format is unknown. Other browsers do not implement this idea as best I know.
