I used it very briefly when I used to use plex, but it works pretty much as it looks. I just didn't see a lot of benifits to that setup as I might as well just use Stremio if I wanted to go that route as this one was kind of a pain to setup. Not sure if you can get it to work "half stream, half download" in the way you want though.. You might be able to script something similar though. Since it mounts the debrid service using rclone, you should be able to transfer out the files locally.
