Hi,
I created a plugin for Plato (
https://www.mobileread.com/forums/sh...d.php?t=314220) that downloads the latest XKCD comics automatically.
It isn't extensively tested, I simply use it. However, it is very simple and it hasn't failed me yet.
Get it here:
https://github.com/everydayanchovies...ag/v0.1.0-xkcd
Read up on the install instructions in the readme (in the archive) or on the release notes on github.
Cheers,
Max
