While it's working, it works great. However, Youtube broke something again in the past week or so and this stopped working... either I get "Batch download interrupted" or it won't find any source even when the video is playing. However, selecting "Quick download" seems to work for either error on some videos, although it seems to default to highest quality video and audio with no way to choose a preferred max size/format. While this is normally good, for 4k videos this can be a pain - I don't need anything bigger than 1080p, so it's just taking up more storage than it needs to.
