I like simple outline mode. In the Emacs development version it folds now with TAB on the heading, so that is maybe one of major options. I could insert "TODO" but is not necessary. Org integrates many things together. But it is not my main note taking application. I am using PostgreSQL for note taking and exporting assignments, tasks, etc. from the database into the Org mode. It is quite different workflow. Org is not collaborative, database is collaborative, redundant, it offers way easier development then trying to handle database things by using text. By the way, people speak "Org mode is plain text", that is was back in time, today Org mode is everything else but plain text.
