I just came across a bug. If you don't make any changes and just quit the app, then relaunch it, it will have a extra library set to the same path as the origonal iPhoto library. Keep quitting and relaunching and you get and extra library each time, with no way to delete them. The only way to get rid of the extra libraries is to delete the Preferences file "com.mac.bwebster.iPhotoLibraryManager.plist" This only occurs when you have not created any other library. Fix the bug and you get five stars.
