I have considered adding something like you described earlier, but I was going to call them "Albums" or "Collections". They would be Favorites that would keep references (paths) to the files stored in different locations, not duplicating the files. You could add items to them by drag and drop, and you could remove them by deleting them (just the reference would be deleted, not the file.)
Would that solve your issue?

I just ran across your suggestion from 2006! regarding collections, but was adVised to start a new thread because that one is more than 120 days old.
What you are proposing, Kirk, is something that I would REALLY love to have in PM. It's the ONE area where I am finding PM awkward to work with, now that I am organising my photos into collections for different uses, chapters in a book, slide shows, portfolios with different subjects, etc . An image might find itseld in more than one collection.
I tried to find a workaround that uses keywords etc, but I could not save those selections as Favorites.
So I'm wondering if your idea is going to make it into the next version?
Thanks
