It would be great if I could create non-gallery albums made of existing images (references to images rather than new uploads)

Does that make sense? What I'm suggesting is a bit like the way faving on deviantart or youtube works, where you can like an image regularly or add it to a specific group/playlist of liked images/videos etc. in this case images and possibly albums that appear in the gallery or /r/ sub galleries. ~lostsemicolon on imgur
