Open and close items in the Library inspector

To work with photos in Aperture, you first select an item in the Library inspector to open it in the Browser. You can open and work on more than one item at a time. When you open multiple items from the Library inspector, you can have each item appear in the Browser with its own tab or have the contents of all items appear in a single Browser. You can click an item’s Browser tab to bring it to the front. You can also open an item in its own pane to view the contents of two items in the Browser side by side. When you quit and reopen Aperture, all items that were open at the end of your last session open automatically.
