I was excitedly looking for how they manage this, but alas, it looks like not well :(

Is there any tools nowadays that:

(a) Lets the user keep Favorited/marked images in a local storage location

(b) 'ages-out' other files to secondary storage pools (removable disks, cloud storage)

(c) Keeps Low-res thumbnails of all images in the collection?

I keep trying to find something that would help keep tabs on a growing collection of images, with growing file sizes from newer cameras, but it all seems like doing it manually is the only way to go :(
