It is great that Document Libraries now support custom Power Apps forms, however When document libraries have Document Sets enabled some problems start. This idea is to increase to support of Document Sets on Document Libraries within Power Apps.
1. The Content type field currently doesn't include Document Set (All document based content types are fine)
2. New forms on Document Libraries don't seem to work (Most likely For documents a document would be created first therefore there hasn't been a need to use New Forms)
