currently it is able to digitally sign pdfs, which evince can’t do

i’m no expert but even though it looks like evince as far as i know is a completely different app build from the ground up

you should try papers. it’s a new app that’ll replace evince as the default document viewer for gnome in a future version. it’s still in development but i’ve been using it for a long time and it’s really good.
