Comment 3 for bug 171429

@Alexandre, I didn't know of LivePen (as descibed at http://www.fontblog.de/kalligrafie-feder-live-pen-fuer-adobe-illustrator), but I like it. However, my suggestion was less sophisticated/complex:

Just change the pen style for (the) selected curve(s) in total. So you can switch letters from pencil written to pen caligraphy.
