Is there a way to see bookmarks in a pdf in preview? bookmarks that weren't added by preview I mean? As far as I can tell there is not.. which is somewhat surprising. especially since they'll allow you to add your own. I mean that's what I would expect table of contents to be, but it doesn't show anything in my file even though in acrobat it has an extensive bookmarked table of contents. a follow-up question would be, is there any free pdf viewing software that is as snappy and responsive as preview (or close!) and will also display pre-embedded bookmarks? because I have a lot of files I like to navigate that way.
