Instead of manually updating the Featured section if/when it gets updated by code.org, you can use this Library I just created to get the status of the public gallery. You can even get projects of a specific type.

Oh, and for the Library section, AppInfo now includes information about the library (if it is one) under data.library. An app with data.library.exists = true is a library.
