Thanks! I was looking for an export button for them earlier today so when I saw you comment I couldn't help myself.
A zip file with all notes in it would be fantastic. I just want to feel like my data is safe from Apple having a bug that wipes it. Read a lot of Catalina horror stories.
IMAP looks promising and might be all I need. Neither Spark or Apple Mail seem to let me export mail as txt but presumably there's a mail client out there that does in which case problem solved. Thank you for point that feature out, should throw it up on:
It's not the ideal solution and certainly not as easy as clicking a button but, for a quick 'n dirty solution, you might look into using "offlineimap" and configuring it to sync only your notes folder instead of all of them.
Please allow me to export notes to txt.
