Comment (by pmetzger):

 So as I said in the pull request, it appears that there's a functioning
 but unreleased gtk3 port of the code now. My current thought is to package
 a development version of claws-mail, disable the fancy plugin in the
 normal version, enable it in the development version. I am actively
 looking at this.
