In case anyone is interested of a similar one using reflux coffee, hapi,webpack with hod reloading (no undo): https://github.com/rrecuero/coffee-react-webpack-hapi-templa....
Redux is very simple and more of a pattern than anything; I do definitely think it's better than Reflux.
So much more can be done with this concept - and it's nothing special - sometimes making things simpler is the best way to solve a problem. Redux is a great example for that.
I've configured it so that it uses hot reloading (only refresh the parts of the web app that changed) plugins that also show the error in the browser while you're developing.
Does that clear it up a bit? :)
I am still not entirely sure what all of those technologies do, but I read the blurbs, and have a very basic understanding.
