Problems with iTunes 11

Apple's iTunes 11 was a definite upgrade in awesomeness and usability but I miss some things from the previous version a lot.

Firstly, there used to be a "Show duplicates" option under the File menu. Now it's gone. Since I have a little mismanaged music library, this option worked great for me to get rid of all the annoying, space-consuming duplicates. Without that, it's freaking difficult!

Secondly, the Search bar in Library. In iTunes 10, the search bar allowed you to make searches even in your iPod. Now it doesn't. It only gives me results from my music library in my PC. And that is very annoying!

And thirdly but least importantly, where is the Cover Flow dude? I liked that!

Thanks for your reading my post! :D
