Pressure Sensitivity added to Pencil Tool
Variable width strokes are great! What would be even better would be to have variable strokes simply by drawing them in with a pressure sensitive device.
I appreciate the tip on using the brush tool, but what I really want is variable widths being applied directly to a simple path. Brush strokes add a layer of complexity that I'd like to avoid because ultimately I want Adobe to add a pressure sensitive pencil to Adobe Draw and have that feature compatible between Illustrator and Draw.

Illustrator's brush system is counter-intuitive and dumb at best... but you can do this with the Paintbrush.
Create a new brush, choose calligraphy then you can set pressure sensitivity to affect brush size.
Overcomplicated and makes me nervous? Yes! But works at least if I need this rarely.
