While I know it can be implemented on the skin side this then means you'll end up with 'Show plot for unwatched items' in Video > Library and ' Show thumbs for unwatched items' in Appearance > Settings > Skin.

EDIT: Ideally it would be in core with 4 states -

• Hide plot and thumbs for unwatched items
  
• Hide plot for unwatched items
  
• Hide thumbs for unwatched items
  
• Show plot and thumbs for unwatched items
  

I'd not make it more complicated than it is. If one doesn't want to be spoiled, turn off everything that could spoile (plot, thumb). So only one setting with either on or off. I really don't see why there whould have to be several states that overcomplicate everything. Actually it's way more easy to just ignore a plot in GUI then a thumbnail that might even spoil in peripheral view.
