Max MSP is definitely an inspiration of mine. Tree Notation is just a format, however. It could be an ideal way for a program like max to store its documents in, as opposed to an xml or a Json. It would allow dual visual / source editing. See our ohayo beta for an example. (note to self: add ohayo demo video)

Large complex code hasn’t turned out to be too difficult yet. The key is well designed tree languages for the task at hand. Also, sublime text helps :). Have some code bases in the 6 digits loc. It’s all about tooling though. I don’t really use folding yet but perhaps that would be another feature that can make things easier, good suggestion. Things like type checking, syntax highlighting, auto complete, are essential.
