That is absolutely stunning, thanks for the great work! I actually saw
it over the weekend before reading your e-mail.

I'm on a plane right now and with limited time, but we should schedule a
call or continue the discussion on the mailing list on the week of the
6th of April when I'm back.

In terms of feedback, the only think that I noticed was that your
functional branch had a noticeable lag in typing and the changes
appearing in real time in the QR code, in comparison to my demo branch.

It might well be that the original branch was simply faster because,
well, it didn't do much :), but it'd be interested to know if you've
noticed this lag and if so, if you've got any ideas where it might come
from and how to overcome it.

Thanks!

Cheers,
David.
