The iTunes 5 Source List
Pierre Igot has some interesting observations about iTunes’ source list compared to Mail’s and the Finder’s:
What if you want to create a new folder the root level? Well, same as in Mail: You first need to make sure that nothing is selected… Hold on a second! In Mail, in order to deselect what’s currently selected in the mailbox drawer, you can click on the empty area at the bottom of the list. Not so in iTunes! In iTunes, you cannot have nothing selected in the source list! So what do you have to do if you want to create a new folder at the root level of the source list? Well, you have to select an existing source at the root level of the source list first—but not a folder! (Otherwise, iTunes will create the new folder inside that existing folder.)
