Add Standard Notes to Notes p 9 -10

[Poecilia]

Hi Matt,
Your book is great - just bought and downloaded it.

I wonder if you know about Standard Notes. It is privacy-protecting and has a number of markdown editors you can select as your template. I want to recommend adding it to the Notes chapter. I migrated from Evernote to Standard Notes a few years ago. It's a good experience.
All the best!
