Hey... Dmitry is working in porting flake to svg for Krita, and improving the vector tools. Not all of his stuff is interesting, but he's also fixing general issues with flake. And since I read that at least two people want to work on karbon, his work might be of interest to them, too. Check the origin/kazakov/svg-loading branch in krita's git repo.
