I agree with the sentiment, but it's a crowded market that if there was an easy, elegant solution that met everyone's needs we'd already have some leaders out there. Maybe we already do. My person preference is Notion at the moment.
That's nice. I used to like taking notes on Notion. But one day, I got annoyed when I was not able to quickly search an old note as it was nested under some other note. Took a while for me to realize and make sense of that.
