Hmmm. I suppose tabbed browsing in preview wouldn't hurt. Those who didn't like it could always turn it off. Submit a feature request.How is the scrolling in the Preview app when viewing PDF files? Is it butter smooth - 60fps? (it certainly isn't in Mountain Lion)
PS: I wish Preview also had tabbed browsing like the Finder in OS X Mavericks.
It's noticeably improved in safari, without a doubt. But it may just be most noticeable on the retina display where it would often lag on heavy websites. It's actually almost too smooth in that it's too fast. It doesn't really skip, just scrolls super fast.It's so smooth, you are advised to wear a seat belt else you may slide off the couch.
ML is perfectly fine for me. Me thinks it's just all the euphoria for anything new.
