View all notes in one feed?

Is there a way to view all notes from different projects/categories in one feed? Should I make all noted “in agenda” to do that? Maybe a feature like that is useful if the last is not the way to do that?

This isn’t possible at the moment without a workaround (for instance by clicking the loupe icon, and next to the search field select a very long date range (say 2 years back and 2 years ahead), then saving this as an overview. We hope to make this much easier in the future and also make it possible to see those notes in an ungrouped fashion.
