definitely an improvement over the built-in pdf reader. I installed it tonight, and I'm still having the problem others mentioned about not seeing an icon for it in the app list. works fine from the x terminal though. Only issues I've noticed so far is that the text entry for changing the page # isn't constrained to only take #s, which would be nice. Also, the backspace key doesn't work. I agree with someone else's comment that having a 'real' full screen mode with no tool bar would be nice. But it's definitely going to be the pdf reading I'm using from now on...
