Scroll bars are AWOL in zathura. I have "set show-scrollbars true" in ~/.config/zathura/zathurarc. I also tried "set show-v-scrollbar true" and "set show-h-scrollbar true" as per what meager documentation can be found out there. Also, no man pages for zathura nor zathurarc. My system is up-to-date, as of about 30m ago...
In case some other gentooer uses zathura, would you share your current experience? Thanks Jorge Almeida
