LineUp 1.0 is a utility application that organizes the Folder Windows that the Finder uses. You may "LineUp" Folder Windows for any mounted Volume, or any Folder on a mounted Volume. "Lining Up" consists of defining a "relationship" between the Finder Folder Window (who's sub-Folder Windows you want "Lined Up") and the LineUp Window. This relationship (difference in TOP location, and difference in LEFT and RIGHT locations) is then applied to all Folders within the selected Folder. The result is a neat and orderly arrangement of Folder Windows on your desktop.
