We are actually very solid with GIS, and decent at coding, but have hit so many brick walls with our app on Web App Builder that we are now forced to try the API for developer platform, though I attended sessions at the ESRI conference in July and found it wildly beyond my ability to program.
We have no other choice because: Web App Builder features have zero css boxes. Why not?
I have code I could use to make the features of our app exactly how I want and have no place to put them.
Switching to the Developer application may not be a great idea, but as it currently stands I cannot group, toggle, or categorize the layer list (left panel), and cannot even change the links at the top of the screen back to a nicer looking code (these links switched back to simple text when the July update came).
Please contact me, I am so happy to explain and have explained these issues to tech support and product developers at Scene online (that product offers so much more for the layer list but we don't need 3D).
