My latest favourite is missing: Note Taking Apps:
Joplin is good for organising text-based notes, so I’m not surprised to see that on your list. But xournal is a for mixed drawing / hand-writing / text, etc. So it’s a different use-case to Joplin. (It would be perfect if Joplin supported xournal notes; so that you could write with xournal and then organise with Joplin. … But that hasn’t yet come to pass.)
