I like the idea of not using heavy electron UIs, but really, I does not matter much nowadays, at least for me.
Important features are synchronized notes, with mobile and desktop support, and syncing should be end to end encrypted. I should be able to link a note to another, include some media, and use markdown, that is easily importable/exportable. I still to this day couldn’t find a good foss alternative to Joplin with WebDAV or Joplin Server (or cloud offerings).
