And even after a lot of practice, it still always takes a few tries to get it right.

I don't know enough about "the LyX way" to be able to have an opinion.

As you pointed out, you can re-export as an svg and then reimport as an image and you're done. So according to your logic, fixing the way to copy directly from Inkscape to LyX is not needed, because there is something else that works. But of course what's the difference with this? It's the same difference for deciding whether to implement this feature in LyX or Inkscape: one takes another step (in your case, saving and reimporting, in my case it would be opening up Inkscape and copying). Also, there are a lot of people who don't know what vector graphic is, much less how to edit one. And at my university, LyX is installed and kept up to date, but we are not allowed to install any other software. Even if we were, some people do not do this maneuver very often. I don't think they would want to install another software to do it. Xu
