folder for shared notes

I’m using Notewise for uni, same as a friend of mine. We both use Cloud to share notes or assignments we work on together, but over the past 2 or 3 semesters the shared notes tab has become cluttered. I see every note we shared, regardless of which course it was for, when we last used it etc. I would love to be able to clean up my shared notes by putting them into folders. Also i would like to delete a note that was shared with me. I know i can basically delete my access to it to “delete” it for me, but that is rather clunky, I’m sure there’s a more elegant workaround.
