Please tell me that "Preview 2" does NOT mean that this is an almost finished version.... I just installed it, so I haven't noticed what the differences are, but at a glance, there don't appear to be any differences. I don't see any new features jumping out at me. Hopefully it will do a better job of syncing, though.
