You may or may not have noticed that there is now also support for =20 subscripts and superscripts being displayed pretty. This is now realy =20= how I wanted scientific note taking to work. Need to make a =20 screencast to show how awesomely this does work. The only thing missing is a little sketch tool in Emacs, fast enough =20 to be used while taking notes... :-) Thanks a lot for you initial implementation of pretty entities - this =20= has been a breakthrough here. Where do we stand with integrating org-babel?
