Emacs buffers are just buffers, not canvas, so dynamic information display is limited, but much can be done and it's already there (see Nicolas Rougier's Nano Emacs as a showcase). You can substitute for instance (push '("#+BEGIN_SRC" . "↦" ) prettify-symbols-alist) (push '("#+results:" . "") prettify-symbols-alist) (push '(":PROPERTIES:" . "") prettify-symbols-alist) (push '(":END:" . "") prettify-symbols-alist) you can avoid tags using in-property-drawer kev/value tagging, that's also easy to query with org-ql. A code block is run by a function as pretty anything and a function in Emacs can be called in countless way, like: - hitting a key - on file save with a hook - when certain conditions happens with a hook And that's in a global or file/buffer-local approach
