For a few years I used Orgmode. I didn’t use Emacs. That is, when I needed to edit text files, I used Vim or macOS TextEdit. I used Orgmode to track my tasks and keep notes. That Emacs was underneath it was purely incidental, and I didn’t use Emacs for anything else. For me, Orgmode was not a plugin. It was the primary software I used, and there was this Emacs thing under it.
Ironically, these days I do actually use Emacs, and I use OmniFocus for tasks, mostly because OmniFocus gets multi-device sync right so it’s worth the price. But don’t hesitate to use Orgmode even if you don’t want Emacs otherwise.
It is hard to sell someone on a solution to a problem that they don't have.
The only unwanted feature you're likely to encounter is automatic sub/superscript conversion, and that's documented and easy to turn off.
I'm not recommending org-mode. I personally don't care if you use org-mode or not. I never understood that mentality. But the type of software you're describing is crap, and org-mode doesn't fall into that category.
I'm a vim user, with two exceptions:
1. SLIME
2. Org mode
There's a vim plugin for org mode that I used to use, but TBH, Emacs excels at org mode.
Which one did you use? I use https://nvim-orgmode.github.io/ and am happy with it, it's fairly modern written as a lua script.
I did see an older one https://github.com/jceb/vim-orgmode but i don't think that's maintained anymore.
I would encourage everyone to try out emacs with org-mode. It takes some time to get used to the editor and its keybindings...
He's literally recommending that everyone who doesn't use emacs should install and use a different text editor.
As a vim user, this is kind of what I have come to expect from emacs users. Honestly, I'm glad that you've found something that works well for you. But I hope that some day you internalize the fact that other people aren't you, and they shouldn't always be "encouraged" to give up their existing solutions to do things in the way that you've decided is perfect.
