Thanks. Interesting. But not really what I'm after -- unless I'm not using it right. When I do M-x org-bullets-mode, it wants to replace heading asterisks with the alternative list
(defcustom org-bullets-bullet-list
'(;;; Large
"◉"
"○"
"✸"
"✿"
;; ♥ ● ◇ ✚ ✜ ☯ ◆ ♠ ♣ ♦ ☢ ❀ ◆ ◖ ▶
;;; Small
;; ► • ★ ▸
)
I wanted something that would give me the ability to add to the existing ordered list symbols -, +, 1. etc., not totally replace the normal heading asterisks.
