You mention Quillpad, so I assume this is for Android. If so, I went through a similar search after dropping NextCloud. I ended up with GitJournal. The app is nice and has all the features I need. I have it backed with self-hosted Forgejo. If I need to make a note on a desk/laptop, I can clone the repo and use whatever text editor I like since it’s all just markdown. I even have vs code server set up for quick notes on the web
“Wall of text”!?!? You fucking kids and your fucking video culture
