The newly added pencil tool in Goodnotes 6 offers an excellent writing and sketching experience, with smooth and intuitive strokes. It would be fantastic to have similar brush settings and handwriting functionality for the fountain pen, giving users the option to adjust it for more stable, precise writing. Currently, the fountain pen feels unstable, and I often find myself switching to Noteful for better handwriting. If the fountain pen could incorporate the same improvements seen in the pencil tool, it would make Goodnotes 6 a more versatile and complete tool for note-taking and sketching.
