[feature request] highlighting
i searched a lot for feature of highlighting in zathura but i didn't get it i didn't know why you didn't add it or where i can get it. mupdf and poppler both have this feature in it. it painful for me to searching for another pdf reader, i tried a lot of them but nothing like zathura, and i need this feature for my school studying, you can provide this feature in plugin or in the main application
