Let's say I download an x264 movie and encode it in x265, when I add it to my library I would like to be able to filter the searches I make of both the x264 file I downloaded and the x265 file I already own. It would be even better if I could filter every version of the same file but that's probably not possible.
And when I download a folder the same, I would like to download everything except already downloaded or owned files.
