Npm start open 2 windows

[DonsWayo]

I don't know if it's an error or it's done that way, but I'd like to know why two windows come out and I can't close one of them have to be open, if I create new components they all start when I run the application?

Yeah its design that way so you can have a better idea on how to handle multiple windows. You can remove it by commenting the createSecondWindow() function inside createWindows().
