I want to use Apple Photos app on a MacBook Pro to organize my photos. I know how to create albums and all that, but my issue is this. The app has a main file Library that holds all of the images. I have albums created and I can drag the images into these albums to sort them. The problem is that the images in the Library don't move out or get hidden upon moving so I have no way of knowing which ones have been moved and which ones have not. The library has thousands of images. There is no way to know if any one of them have been moved. Fortunately, it won't create a duplicate, but still this is no good if I can't know what I have left to organize. Thanks for any help.
