So, I've had inkscape (1.0.2-4 on up to date debian testing) crash on me so many times in the last week, in ways that cost me several minutes of work each time. So I've stopped using it for anything.
I appreciate the exhausting amount of work that goes into something like Inkscape, but holy crap. Segfaulting on me. Or leaving a foregrounded window open with no content in it that I can't close and that blocks the rest of the program until I kill -9 it. Very frustrating when I was trying to get real work done.
Arc from 3 points, add tangent/normal to a curve on a determined point, measure length of polylines and splines, measure area of polygons arcs and ellipses, measure angles, library of elements, all the 8 snapping modes and indication of what each mouse button will do.
Nice! So, I think the UI must make these features more obvious.
Another thing I miss in inkscape (in case you know): I sometimes did some very interesting interactive live geometric demonstrations with Kig. Had inkscape had the same features, I'd use it.
Also, I wrote a small library that lets me programmatically generate SVGs with Python. This lets me create very precise vector images. This fills some of the same needs.
