IOS suggestion: Sub folders within hidden folder in Photos App

This is more a suggestion than a question.

The option to create sub folders within the Hidden Folder is a key feature that is currently missing.

Now that the Hidden Folder is password/Face ID protected, it now makes sense to start using it over a 3rd party app.

However, the Hidden Folder is currently still missing key features like sub folders and sorting options (i.e. alphabetical or date/time).

Next iOS update? 🤞
