This was a nice little reading!
I’m new to Legend and although I knew all the features you described, it was a quick overview and I agree Legend should be more popular!
I’ve been searching Outliners and similar app for more than a year. I Started with Workflowy and still use it to this day because of it’s simplicity but that’s also why I’m looking for other options… To get more done in a single app.
In the past year of research, I don’t recall any appearance of Legend (or Moo.do). Well not in a way that got my attention at least! And I’ve seen and tried a lot of them, Dynalist, Logseq, Checkvist and workflowy were probably the most popular in my findings until recently when Legend finally got my attention!
Now I’m trying to see if it can really do it all and how I can bring my existing system without destroying all the organisation I built in the past year!
