CNET has an article on the 7 features Apple dropped from iTunes 11. These are Cover Flow (which I don’t miss), de-duper (now you need to use 3rd party applications, the excellent iTunes DJ for creating easy continuous mixes, Gapless Playback Editor (works for old Gapless albums, but not new ones, so all my new live stuff will have gaps), Multiple Windows (as you can tell from my previous post my other biggest piss off), the other Sidebar (which was just a link to the store and I will not miss) and quick volume control in the mini player.
I hate when Apple upgrades and removes features! It is the dumbing of the Mac and I don’t like it!
And honestly so far I haven’t been so impressed by the much vaunted speed of iTunes 11. Maybe my library is too big, but scrolling still does not seem that fast to me.
