I’m not a heavy user; when I use it, I’m coming at as a novice, usually with a specific task in mind and I find that I might as well have Inkscape open on half the screen and Google open on the other half as I have to search for how to do anything. Once I find it, it works fine, but the UI seems the exact opposite of approachable for me. (It feels in many regards like Gimp was 10 years ago; I have no idea if Gimp got better because I gave up on it with enough good alternatives. Inkscape is better than that, but it gives me the same feeling of “does this really need to be this hard to import a multi-color SVG and make a slight touch up?”)
