@rl_dane was bothered by #calibre's new AI features, I poked for a bit and found out you can hide most of it. Out of sight, out of mind.

This is a short #tutorial just in case you want to do the same.

This is day 41 of #100DaysToOffload

I was not particularly bothered by these, but a friend was so I poked around and figured out how to hide all the AI stuff from Calibre.
