QR code: option for symbols and path data difficult to use

It's not easy for the average user to find out how to include path data and symbols for QR code generation in the extension.

The path data I copied from the XML editor was not accepted. For how to generate relative path data correctly, I'm at a loss.

The symbol option works, but it's also hard to know from just the GUI what to enter (hint: it requires a user to hover over the symbol in the symbols dialog, read the symbol name from there (a string like 'symbol22582') and then to put that with a hash tag in front of it into the field that asks for a url).

I would like to suggest that the extension accepts a single object as input, and generates the QR code from that, if the option to use something from the canvas is checked. It should not tamper with the object's size, and it should use clones, instead of writing it all into the same path. This would allow the user to change size and color after the extension has been run, and it would be easy to use.
