It would be super helpful if the site automatically recorded start date and end date when you change the status accordingly. For example, if I change the status to complete it would be nice if a date was auto recorded. Also, the ability to filter the dates would be helpful. I cant tell what I watched in the year if I dont manually record it. It would be also nice to have a place that organizes dramas you have watched by year. Currently I manually do that with custom lists because this option isn't available.

I second that. An automatic recording of starting and finishing a show or a movie would be helpful. An additional column in the watchlist with the date of finishing would be very helpul, too.
