I'm posting this so that people can see what I'm talking about, in case it helps.
The inkscape version has two issues I'd like to resolve if possible.
1. The lack of line width variation, in particular, the tapering at the beginning and ending of lines.
2. The shakiness of the lines.
The two problems kind of go together. The shakiness seems to be caused by the fact that I'm drawing the lines fairly slowly, so relatively lots of nodes are being laid down. If I draw the strokes faster, they are smoother, but then I can't follow my penciled guide drawing as well. I do realize that I can reduce the number of nodes after the fact, thus yielding smoother lines, but this solution is time-consuming and tedious. I'd prefer to be able to adjust the number of allowed nodes downward on the front end.
Also, drawing the lines in a quicker fashion does help out with the tapering because of the thinning setting's capabilities, but again, I can't follow my guide drawing as well.
So, I either need to learn to draw well at a high stroke speed :D or I need to figure out how to tweak the program so that a slower stroke speed gives smoother lines and better pressure sensitivity. Since I'm fairly new at this learning to draw business, maybe the problem will resolve itself as my skills improve. In the meantime, I'm hoping for a tweak fix. :D
