I realize this is a little different, but I wonder if it's possible to easily modify the plug-in to automatically play a different file when other playback stops. The usage case I'm thinking about is Loopback. I'd like to be able to have loopback on whenever i'm not playing something else. That way when I stop playing a movie within J River and go to an online service (say HBO Go), it will play through loopback without me having to actually select loopback.
Hopefully that made sense. Also, if there is an easy way to do this with current functionality which I've missed, please let me know. I'm using v18.
