So right now with custom channels once setup, If you start to watch a movie or show but want to come back to it you have to remember where were in that show or movie when going into the library.
It doesn't track back to your actual library.
Idk I know the channels are supposed to be like live TV where they don't necessarily track back as well, but since this is from my own library I think it would be something I would like to see.
So Not necessarily changing the functionality of custom channels so it's still is like live TV but when I go into my library that showing the progress I was in while playing "live TV" via custom channels.
