Noobs keep asking for this feature almost daily now and pg kills the post every time, because you're not supposed to ask like this. Feature requests go in the feature requests page at the link in the bottom. Or just upvote the link by gauravgupta, it's on that page.
Not that I want to dive into 'yet another typical silly internet argument (TM)', but those seems to me to be tongue-in-cheek geek references whereas your comment carried the immature snark of 'lol you n00b' which I come to hn to avoid.
I'm afraid you're looking for something that just isn't there. Now this feature request is a good idea in my opinion, that's why I'm suggesting to upvote it on the Feature Requests page and not just make another post that will get killed and ignored.
I think it is a really bad way to gauge community interest on the feature requests page because very few will see it. Not much in the way of features gets added to HN so its only like to happen if pg and co decide it themselves or there is a heap of community interest.

Looks like a great viewer, but the library function looks like it requires me to import everything I have, and then import new stuff as it comes along. That might be slightly faster long term, but short term looks like a major issue. Unless I'm missing something?
Hardly, there is a lot of arc that you are not seeing that really powers the voting and other features of the site like spam detection and voting ring detection. It's similar to the code at http://ycombinator.com/arc/arc3.tar but there are significant modifications as well.
HN does not use Google Analytics or any other kind of analytics tracking for that matter. I think they used to use mixpanel and had the mixpanel logo at the bottom of the homepage before though.
