Do you really need a first-class-editor for working directly from the canvas? Wouldn't it be enough to use the canvas just for navigation and show a rendered picture of the code, but open a separate editor (maybe side by side?) for the real work?

My understanding is that Haystack's mission is to explore this design space more fully than others have before, so I think they're making the right decision to be audacious here!
