I love the search embedding feature. At work, I create daily notes, take my meeting notes and create To-Do lists in the daily notes.
To keep track of my incomplete to-dos I created a new note that embedded the search for “- [ ]”. This way I can go to the To-Do note to see all unchecked checklist elements, and which day they belong to!
Works better than any note-taking/ task-tracking app I’ve ever used.
