Hey Shala Pascucci thanks for asking. We do plan to have custom fields for notes in future. So that might solve what you are looking to do. You could create custom fields to categoriese and add structured data to notes.

Matt Byrom Would this be folders just for files or would there be folders for Notes too? If not, could that also be a request?

This is an essential one as far as I'm concerned.

And allow downloads of these folders

Yes please!
