Tangent, I've written many note taking apps (Chrome extension, Android widget, desktop app, web app, PWA, mobile app, etc...) my central local API (running on an RPi) the MySQL db went down and also my node pm2 error-log file grew to like 14GB taking up my whole 16GB sd card... later had to move this tc.log file to get MySQL running again, pretty funny. Otherwise been running solid, it's an htmlcontenteditable type so you can drag/drop images and it renders them. Issue is the caret position that can be problematic when you lose your position same for a regular textarea input.

I was lazy the images are converted to base64/stored as such so like 30% growth in storage vs. hosting/url.

What I still have to setup is a centralized store/preferably statically encrypted and remote/syncing.
