add Gtk3-Mushrooms as optional dependency or even Use it by default
Someone made a Gtk3 fork, which revert many changes made with adopting gtk3 and CSD: https://github.com/lah7/gtk3-mushrooms. I think most xfce4 users really prefer the classic look, so it should be at least A optional dependency, so users can find it more easily. Maybe even consider enabling it by default.
Sorry if this is the wrong repo for this suggestion, I'm new on this GitLab, so I'm not sure how the tasks are sorted
