My PlayOn subscriptions continually fail and need to be removed if I want to silence the 'failed subscription' naggings. I would request to have the option to disable a subscription, in addition to just deleting it. This would have the effect of keeping it in my list so that I can easily see all the shows I'm tracking and then I could re-enable a subscription when I know
that the show has returned. It would also show me the original source of the subscription so that I can know which 'channel' to go back to if needed.
