>Next on our roadmap is the development of support for albums and automatic categorization based on photo types, such as screenshots. We are also working on integrating on-device machine learning to ensure that you can enjoy all the smart features you’ve come to rely on while maintaining end-to-end encryption.
Once it has matured a little more, and this feature is implemented, I'll happily switch from Google Photos!
