@jasongilman: I talked with the ink team about the loading widget but they now use a loading bar on the bottom. I tried it but in my opinion it is not clear enough (see here: https://files.gitter.im/JunoLab/Juno/OHJC/loading.png) as I totally overlooked it until I had saw the previous picture. They also linked me the source code of the old loading widget (see here: https://raw.githubusercontent.com/JunoLab/atom-ink/master/demos/eval.gif). I would like to know your opinion on that matter. I would prefer the old loading widget but that would mean that the code would have to live on proto-repl itself not on atom-ink, meaning, one more (possible) thing to maintain.

@carocad: I'm ok with it going in Proto REPL source code. I've done that with the tree view from atom ink already since I made some Proto REPL specific changes to it.
