I tested it with Löve and syntax highlight and debugging with breakpoints works great. Now that MS made VIsual Studio 2013 CE available for "free", it's an real alternative to Zerobrane Studio.
Both have neat features, but when you compare Babelua+VS2013 to Zerobrane Studio, I would say, debugging works much more robust. On the other side Zerobrane Studio has livecoding, but personally it's not really usefull like the way it's working. So this is no pro for me.
