The bulk of TWF could be published as a book, and amount to zanier intro to category theory than many formal expositions. QR codes for links.
To include links that are readable by mobile devices: https://en.m.wikipedia.org/wiki/QR_code

I see. Yes, I guess I have to think about mobile devices!

In hypertext, you could just have a link. In a print version or a published book it would be nice to make the references (given how many TWF has) followable without too much rigmarole.

so QR codes for URLs in the margins so printed versions don't get cluttered by transcription errors and the text isn't hampered by long URLs.
