I have successfully installed the Web AppBuilder Developer Edition 2.0. I have added Robert's Widgets (and some of Larry's too). I have successfully built my first app (much easier than I expected, once you get the hang of it, it's easier than Flex). This app references an AppID in the signoninfo.json.
Question:
I need to build 6 different apps all with different layers. I can duplicate the app I created in the WAB inside the Developer Edition GUI, but how do I remove/add layers?
