Drawing on PDFs - Brush size

[Gonzo]

When drawing you can change the size, however when you are drawing you can't "see" how big the brush is.. makes it hard to draw.  Suggest having an outside line of the brush size / area.

I'd like to add that I think the Draw functionality for PDF files could be improved.

Currently, if you draw a line and then change the line thickness, the thickness of the line you have already drawn is updated, while the next line is drawn using the previous thickness. This behavior feels unintuitive.

I think it would be more logical if changing the line thickness only affected future drawings. For example, if you set the line thickness to 1 px and draw a line, then change the thickness to 2 px and draw another line, the first line should remain 1 px thick while the second line should be 2 px thick.

At the moment, the behavior is reversed: the first line becomes 2 px thick, while the second line is drawn at 1 px.
