Would it be good for federation? As in ability to dump a large amount of mixed quality images on a local instance and then sync only a subset ("tagged favorite", "rated 4+ stars" or something like that) to an off-site instance. Because that's my number one requirement for image management: convenient management of the image selection subset pyramid. I know nextcloud has some federation features, but I have no idea if that could be put to work based on some exif criteria or other file metadata. For all I know this could be a killer feature that would be enough on its own to motivate the nextcloud plugin vs standalone decision, or it might be completely useless as in federation only based on entire folders.
