Unwatched Only View

Hello
sometimes I want to see only the watched movies in the list. I used to use the the Transparency! Skin, and in this you could choose to show Unwatched, show Watched and show all movies.
I’m missing that feature on Confluence. I do prefer the confluence design so I would like to keep it.
I’ve been trying to play with the skin’s xml files but haven’t found the proper option, I just found the watched toggle button on the MyVideoNav, but as I understand it, that only defines the button, I’m not sure where the action is actually performed. It would be great to change this.

Another solution would be to assign a shortcut key, but I don’t know what the name of the action would be.
Anybody has any ideas?
