This is great to help get out of OneBloat. I feel bad for the people that seriously committed to it. Hopefully it'll be a good lesson about why the markdown approach is so much smoother than a proprietary format.
But yes all that supported stuff is great, but man those things at the top. Dealbreakers.
That might be nice for read-only notes, but for notes that I'm going to read sometime down the line, I need structure. Org-mode is great that it enables both structure and free form. And once one gets in the habit of enforcing on himself structure, his notes become clearer to himself months or years down the line when he rereads them.
For instance, I have been sent many a Mindmaps for the sake of the name exported from tools but just branches of terms which would have been better off as a list.
Recently, I have been teaching my daughter the idea and the art of taking notes. She is allowed to use any tools she like to try out. I have so far told her about Obsidian, VSCode, and Sublime Text. Of course, Apple Notes is there too.
My big gripe is that most of my task management and notes are done via my phone or tablet like a clipboard, and management of plaintext on these kinds of devices tends to suck versus the UX of say Todoist with widgets to display tasks on a launcher. But the likes of Todoist are appalling feature-wise.
What I really want is the concept of preceding and blocked tasks, and to only be able to surface currently actionable tasks. AFAIK, TaskWarrior can do this, and IIRC, similar can be done with Org-Mode with TODO dependencies.
