I'm a long-time user of free/open source software, and write various things for both fun and profit. I don't take myself all that seriously and I do all of my own stunts.
You can find me at these fine establishments on the web: Open Source Musings, The Monday Kickoff, Weekly Musings. and The Plain Text Project.

You've hit on a good point: not everything is a good fit for everyone. Turtl doesn't meet your needs, but I know a few folks who've embraced it. Is that a good thing or a bad thing? Neither. It's just the way things are.
Not that it matters, but Laverna or the Notes app in Nextcloud.
