Thus we need a 'calligraphic input' button (maybe with a stylus pen icon) which toggles between pressure sensitivity plus maximum line width - and no pressure sensitivity plus the line width you choose in your tools menu.
Also, when shape recognitions intervenes, lines get the width set in the menu. So it could be nice to be able to separately choose the width of shape lines, so that you could simultaneously scribble text in calligraphy, with pressure sensitivity, and draw lines and circles with thin lines.

BTW, you're great anidel!
