Add a watched icon to your personal collection lists. This might help when trying to decide what movie to watch and just to keep track of what you've seen and what you haven't. Also, make it so you can turn it on/off, once you've seen everything then you can start over, or if you accidentally set it to watched, you can change it back.

I second this, as I often look at my collection on lddb when trying to decide what to watch. It's better than holding my head sideways saying "nope" over and over again.

this is a nice idea. they have it on Blu-ray.com

I use the "Date" field in the collection for this.

No date means "not yet watched" and when there is a date, it means that I can tell potential buyers when the rot level was last checked. Better than a simple watched flag.

Other people might choose to use that field for the date that one acquired the disc though.

Actually the "date" field was made for that: to track the last time you checked/opened/watched something.
