It would be very useful to have **more pen size options** or, even better, a **slider** that allows users to choose the exact line thickness when using the Pen tool. Currently, the limited preset sizes make it difficult to create **detailed drawings** , especially when working on diagrams or construction-related sketches where line variation is important.

As someone who regularly works with technical and architectural details, I often need to represent **different types of lines** —thin for guides, thicker for structure, etc.—and sometimes combine that with **opacity adjustments** for layering or emphasis.

Adding more control over both **line thickness** and **transparency** would make the drawing tool much more powerful and precise for professional use.
