I would find it helpful if there was an easy way to check when something was watched.
- Might come in handy for those that want to adjust the new collection.
- Parental oversight (maybe add which player it was on.)
- Big-brother types.
- Those of us who think they've watched something, aren't 100% sure, and would rather avoid getting halfway through (particularly the longer TV shows) before realizing they definitely remember it.
