I can sit on the couch in front of my tv and pick a movie for download on my phone, or check if the next episode of something has been automatically downloaded yet. I think that sonar does a pretty good job of TV series management, like I don't want to download all of Doctor Who because I'm only on season 3 on a rewatch right now. All I needed to do is add the series and deselect the ones I don't want currently, bam I have it on Jelly fin
Also I was able to take a drive with two terabytes of stuff I've already organized myself and import that as an existing Library using Sonar and radar Charlotte
