That's the one feature I'm still longing for. As I front end developer I've spent several days reading webpack's docs trying to make it work. It's a fantastic tool but I hate to mess with it. I've even considered leave the field because of how dreaded I felt when dealing with its configuration. I felt like I was not doing real work, just trial-and-error my way out.
It's really not that bad once you get your head around it. Thanks to it you can do some pretty neat things.
I only strayed from pre-made webpack configs once.
