I would like to suggest expanding the pencil tool in GoodNotes by adding a full range of pencil hardness options, including:

12B, 11B, 10B, 9B, 8B, 7B, 6B, 5B, 4B, 3B, 2B, B, HB, F, H, 2H, 3H, 4H, 5H, 6H, 7H, 8H, 9H, and 10H.

In addition, it would be great to include a mechanical pencil (sharp pencil) tool, which would be especially useful for precise writing, diagrams, and technical notes.

These additions would provide users with more realistic and flexible drawing and writing experiences, similar to traditional pencils.
