After some Googling I've come across http://foldr.org/~michaelw/emacs/ http://foldr.org/~michaelw/emacs/ which includes a hack for giving nested s-expressions different colours and hiding the parentheses. This sort of "tree view", combined with paredit's "tree editing", might go some way towards faking a tree editor. Maybe this could be combined with https://github.com/jacksonrayhamilton/context-coloring https://github.com/jacksonrayhamilton/context-coloring and either https://en.wikipedia.org/wiki/Semigraphics https://en.wikipedia.org/wiki/Semigraphics or the new cairo support for drawing pretty borders?
