Title: Allow recipients to organize shared notes into folders

When someone shares notes with me, I can access the shared notes, but I cannot create folders to organize them on my side.

As the number of shared notes increases, it becomes difficult to find and manage them because all of the received notes remain unorganized.

It would be very useful if recipients could create their own folders and organize shared notes into those folders.

Ideally, this folder organization would be personal to the recipient and would not affect the original folder structure or organization of the person who shared the notes.

This would make managing a large number of shared notes much easier.
