I'll also add that there is an editor that I think basically is the "holy grail": * super fast/responsive * inline/contextual UI * automatic transmogrification (s to ULs, ``` for code blocks, etc) annotations * revision tracking * collaborative editing * image uploads + formatting * table insertion + editing * task lists * attachments It's Dropbox's Paper editing component, but I don't think that's going to be open-sourced anytime soon.
