I did look at that a while back but could never get it to work so gave it up as a bad job (bit like the svg output from gimp LOL)

I generally do tracing by manual path placement using bezier or such. rarely use trace bitmap unless it's a large clipart type image where it will trace flat colours etc. but normally it's quicker to just click around the shape and place the nodes.

Btw. there *is* a centerline trace extension for Inkscape (but it
appears to be difficult to install on Windows, so no guarantees):

(it worked great for me when I traced a kirigami pattern)
