I would like to move app.js and routes.js from the config folder to the root of javascripts folder next to views, controllers, models, helpers, etc. I think that makes more sense to have it there. Also routes.js should really be router.js. But as it stands ember build looks for those files, with that exact filename, in the config folder.
It would be nice if we could customize the file and/or folder path inside the ember.json.
