Kod app is a promising code editor for OS X, created by the Swede (wohoo!) Rasmus Andersson. A bunch of features are promised, and the big news is that Rasmus today announced the project open sourced at Github. Great stuff. There's also a beta out if you want to try it out. I think it's awesome with a new simple, light-weight editor that's actually maintained. If Kod gets versatile, flexible, great features and highly customizable, I think we've got a player.
