Thanks for the info Alex!
Sorry, I wasn't being clear enough - actually, I'm trying to avoid being the early adopter on this one... I haven't tried to install. So as far as I know at this point, it works perfectly! ;-)
But looking forward to doing that install, I was wondering how that works, but your answers clear that up for me.
In fact, that additional info makes me all the more interested in trying it. If I get a block of time when I'm feeling adventurous, I may go ahead and try it. It would be really great to get this improved readability of pdfs. It's quite exciting actually.
