It would be great if GoodNotes allowed users to rescale existing paper templates. For example, when using an A4 template with a squared pattern, users could adjust the grid size (e.g., 4 mm, 5 mm, 1 cm, etc.) without changing the overall paper format. This flexibility would make it easier to customize templates for different needs—such as technical notes, sketches, or graphing—while maintaining a consistent page size and layout.
