In general org entities work wonders, and I'm a very happy user.
I have a couple of others things that could be made nicer (somehow).
'===>' indicates what would be nicer:
- \frac{x}{y} ===> [(x)/(y)] or something similar. You'd need to be
able to see that it was folded, somehow, e.g. '[' could have
another color, or the background of (x)/(y) could be different.
- \bar{x}, tilde{x}, underline{x}, ... ==> constructed using
combining utf8 characters ¹ (or at least support of it; i couldn't
get it working properly)
- Being able to specify several white spaces (it seems not to work,
e.g. below I would like to replace quad with " ␣ ", but this
doesn't seem to work...).
- perhaps overlay to indicate when something is folded/replaced with
a utf8 character.
Here's my org-entities-user btw:
(setq org-entities-user '(("space" "\\ " " " " " " " " ")
("implies" "\\Rightarrow" t "⇒" "=>" "=>" "⇒")
("iff" "\\iff" t "⇔" "<=>" "<=>" "⇔")
("succcurlyeq" "\\succcurlyeq" t "≽" ">=" ">=" "≽")
("gimel" "\\gimel" t "ℷ" "gimel" "gimel" "ℷ")
("beth" "\\beth" t "ב" "bet" "bet" "ב")
("coloneqq" "\\coloneqq" t "≔" ":=" ":=" "≔")
("eqqcolon" "\\eqqcolon" t "≕" "=:" "=:" "≕")
("cdots" "\\cdots" t "…" "..." "..." "⋯")
("colon" "\\colon" t ":" ":" ":" ":")
("quad" " " nil " " " " " " "␣")
("geq" "\\ge" t "≥" ">=" ">=" "≥")
("suchthat" "\\suchthat" t "|" "|" "|" "|")
("leq" "\\leq" t "≤" "<=" "<=" "≤")))
All but suchthat are normal LaTeX characters.
Perhaps, org entities could use the TeX input method as a souce of
symbols? See:

When the facts change, I change my mind. What do you do, sir?
