I barely scratched the surface of what org mode can do, but tree structured todos were a game changer for me. When programming, researching a problem, being forced to go down a rabbit hole it helped me go as deep as necessary into a task without loosing track of what I actually want to achieve.

I wish there was a great hierarchical todo manager for native Mac, with the capability to paste images. Right now I use taskpaper, which lacks image functions. I tried notion, but its editing capabilities are really slow.
