Currently juggling my book in 3 formats:

- an epub of my finished Draft 2.5 that I've been annotating in Apple Books while reading/editing;
- editable markdown files with my outline and manuscript, to transcribe my notes from Apple Books, in an SSH window;
- and my notebook and fountain pen to draft new sections, by hand, that I noticed I needed to add.

I'm enjoying this third draft, even if my process is unorthodox.
