Yes, it seems like a really recent term to me. I first heard it when the writers strike began and never before that.
When I think streamer I think of people on Twitch or YouTube who stream themselves. No idea where calling streaming services/sites "streamers" came from but it always confuses me.
I know on Windows there's settings to enable moving torrents automatically when the category changes. Also make sure to enable automatic torrent management otherwise I don't think it will work properly.
I'd also check the default download paths too, there's also a setting to keep inprogress torrents in a different spot. Hope that helps
