Have Libraries with Bookshelves to store the Notebooks

what if goodnotes did not have FOLDERS but shelves and libraries. Example: i may have a "personal" library, a "work or professional" library, maybe one for my "clubs", and one for the uni or school.

in the "school" library i may have a shelf for chemistry, one for biology, maths, languages etc. on the "language" shelf i might have notebooks for Eng, French, German, or Grammar, or Literature Autumn Semester 2021 etc...
