I've just discovered that OS X has a lot of nifty thing built-in which some applications take advantage of, and some applications reinvent the wheel (and sometimes get flamed for it on macupdate/versiontracker, especially when they try to use non-native Save windows).

I wonder which route LX will take, since it uses a lot of non-native widgets.

Perhaps the most interesting feature is the ability to print any document to a PDF, natively in OS X (without the need for any Adobe product at all). I read somewhere that Quartz (?), which draws everything on the screen, does this using PDF... did I get that right?

I also wonder how file thumbnail support will be handled across XP/Linux/OS X...

I guess it's still far off and perhaps not even relevant, but I wanted to make the forum post anyway, if nothing else, perhaps to evoke a thought or two.
