Nice... works well, and fast. Rated 4 out of 5 stars

The only thing that I would like to see in a future version is maybe a tooltip or other way of displaying the encoded URL, which is a nice way of reassuring yourself that you grabbed what you intended to before bothering to scan with a phone. Also, the borders in 0.6.3 still appear in the UI color instead of white for me, although this didn't keep it from working in my case.

This review is for a previous version of the add-on (0.6.3.1-signed). 

Borders should be fixed in 0.7
For the tooltip to appear just hover the QRcode.
Thank you, it really is a good feature! :)
