I really wish the library had the same kind of functionality as links links do in Indesign. "Go to link" "Relink" "Edit Original" "Reveal in Finder" etc. I know the way Fc works now links are embedded into catalyst so a "Reveal in Finder" wouldn't really make sence, but maybe it could be changed to work more like Indesing in that regard. There could always be the option like in Illustrator to embed the images into the Fc document if desired. At the very least you should be able to open images in photoshop right from the library to make edits without destroying components and transitions that are related to that image.
