Neat. It took me a while to figure out how to "undo" the slide. First I tried clicking the link that triggered the slide, then I tried clicking around the side pane itself, then I looked for links that might close the side pane, then I finally clicked the original page and it slid back into focus. And, that's the unfortunate problem with cool javascript UI enhancements. Unless they win the javascript lotto and become really popular / prevalent, users often don't know know what to do... Which is a shame. But, nevertheless, nice effect.
