Use Stacking to keep your photo collection visually tidier. To work with photo stacks, use the commands available in the toolbar for the Information panel, or in the right-click menus for thumbnails in the Browser, or from the main menu: Organize | Stacking. After selecting a group of photos in the Manager, use Create Stack. Stacked photos are listed as a single item, and a stack can be worked with as if it were a single photo. At the top right of each stack is a number indicating how many photos are in the stack. Click it to collapse or expand the stack. To visually represent the stack using a different photo than the first one in the list, select the desired photo and use Set as Main File in Stack. To unstack files, select at least one file in the stack and then use Unstack.
