I've been using Trakt for a little while and find it super cool. There are many plugins and it really helped me to automate the tracking of what I've watched.

But I personally don't care about the number of times I have watched a given tv show episode/movie (nor even the when). The only thing that matters to me is to know whether I've seen something.

It actually bugs me a lot to see something like "8,332 episodes (8,334 plays of 97 shows)"

Some time ago I synced a Plex server with Trakt and it marked everyhting as watched again. It took me over an hour to rematch the number of watch to the number of episodes.

Therefore it would be really nice to have the option to mark things as watched only once and discard any new watch.
