Can you clarify what you need? Are you just looking to open a parent or child heading, like C-RET or M-RET but at higher/lower level? Because that’s pretty trivial in elisp:

(defun org-insert-child ()
   (interactive)
   (org-insert-heading)
   (org-do-demote))


(defun org-insert-parent ()
   (interactive)
   (org-insert-heading)
   (org-do-promote))

Oh I see. What do you mean by “dark mode is a myth”?

What are you talking about?

How did you do the number incrementing?

Makes sense. I tried to keep my buffer list clean at first, but kinda gave up cause so many things in emacs create buffers

Curious why you prefer killing?

That's the ticket! Thank you!
