Thanks, @Mykle1. I’m definitely familiar with that list, but none of the modules support shared and remote notes, at least that I can tell.
If it was only me adding the notes, it’d be easy, but I also want my family to leave notes for me. Afaik, nobody else can modify or share Gmail notes.
I also want anyone to be able to edit it while away from home, so I need to use an external service (a la Gdocs, DropBox). I think a Telegram bot would be good, except nobody in the family uses Telegram either. Maybe I’ll need to write a Twitter DM bot. ¯\_(ツ)_/¯
Finally, because this extends into online services beyond the mirror, I asked the forum because you’re a bunch of smart people!
