Code folding methods
There are two code folding methods, evil folding (the default) and origami. Evil fold is recommended for Clojure development.
Origami adds a recursive open and close and what it calls an org-mode header collapse (didn't seem to work on Clojure code). Origami seems less useful for Clojure than evil-fold, as folding seems to only work at the top level.
Origami allows you to write your own parser to teach different ways to fold code. Origami is a great choice if you want to customise your code folding.
