Ideally, I would like to see an abstract view as well as collapsed titles and full note views. It make sit easier to scan historical notes that are related. Currently, if you have a couple of long notes, you have a lot of scrolling to do. If you don’t have detailed titles, you may not get the full gist of it from scanning collapsed titles. That said, collapsing all titles would be nice.
For context, I imported all of my Evernote notes into Apple Notes and then from Apple Notes into Agenda. So, I started my Agenda journey with a few thousand notes.
