Thunar 1.8.0 is finally out, complete port to GTK3. https://git.xfce.org/xfce/thunar/plain/NEWS Could be nice to have it in portage :-) Reproducible: Always
Its in the tree now. its still masked tho because it has dependencies that cant be keyworded just yet (they are going to release a couple other things soon then we can drop the mask)
