Independent Opacity Control for the Pencil Tool
I’d like to suggest that Goodnotes add an independent opacity slider for the Pencil tool, allowing users to adjust stroke thickness and opacity separately.
Currently, in the standard version of Goodnotes, increasing the pencil thickness also makes the strokes lighter and more transparent. As a result, thicker strokes appear gray and faded rather than dark and clear. This is quite frustrating, especially when I want to use thicker pencil strokes while maintaining their original intensity.
Interestingly, the China version of Goodnotes already has an opacity adjustment slider that solves this problem. Users can set their preferred opacity independently, so even thicker strokes remain dark, crisp, and fully opaque.
It would be great if this feature could also be introduced in the global version, giving users more control over their handwriting experience without having opacity automatically change with stroke thickness.
