I see that https://specifications.freedesktop.org/menu-spec/latest/apa.html says 'Science' is a top-level menu. However it doesn;t appear by default on my xfce desktop. Does it on others? Can an app arrange to add this menu? (Several of my packages are best listed under 'science', and if they are installed I'd like there to be such a menu section ) Wookey -- Principal hats: Linaro, Debian, Wookware, ARM http://wookware.org/
