I'm probably the minority, but I used coverflow when listening to music on my computer. I liked being able to glance at my screen to see what album was playing when I shuffled my music. Also, they have gotten rid of the now playing window in the lower left. I used this for two things. First: Like coverflow, I was able to see what album was being played.
More importantly to me, it would show the name of the current chapter in a podcast. I used to have iTunes behind all other windows, with just the bottom inch or so showing so I could see the name of the current song on my music podcasts in this window. Doh.
2: When adding new artwork to tracks (I prefer to add my own artwork), I could just drag and drop the artwork into this window and add it to multiple tracks at once. This option is now gone. Now I have to select each track individually, go to info, select artwork tab and add it. That is a pain in the buns when adding multiple tracks to my library. Does anyone know of another way?
You can select multiple tracks at a time, go to info, and drop the artwork in there. That's how I've always done it - didn't realize you could use that other window.
