Hi; This is the first time that I've installed CentOS 7.1 with a GUI (I've just used a CLI previously). I'd like to read a pdf file and I don't see any pdf reader applications installed by default. This seems unusual to me. So I see that gs is installed, but it doesn't really work very well for me as I can't seem to scroll to the next page. So what pdf reader application should I install (preferably open source) that will install itself to the menu along with Shotwell? It looks like Gnome desktop. Thanks, Ken Wolcott
