A new update to iTunes on Thursday adds two new features to Apple's MiniPlayer and improves performance for users with large libraries.
Version 11.0.3, which went out as a free update on Mac and PC, has a new feature that lets you tweak the MiniPlayer to show album art with the player controls hidden. When you mouse over the player, the controls fade back into view. It also brings back the MiniPlayer progress bar, one of a handful of features Apple took out in the jump to iTunes 11.
Other changes include now showing album art in the songs view and putting multiple disc albums together as one album when in album view. Apple also says the update improves search performance and sorting when a library is "large."
Apple's last iTunes update came back in February and added a new "composers" view and sped up syncing large playlists. You can see the changes to the MiniPlayer in the animated GIF below:
