Tracking of watched movies etc

Hello,

i'd like to keep track of what i have watched already. Over the years i've watched many movies etc; too many to remember them all. Which isn't good, because i'd like to watch all movies from some actors/directors etc. So i always have to think hard, when i go through the lists of those people, which titles i haven't watched yet. I have to watch trailers or read the plot to remember, which both i hate, because it costs time and i don't want to be spoiled.
By reading some of the articles on here, i came across the check in feature, but that doesn't fulfill my needs completely. It only helps a little, that i can see - after selecting a title - that i have watched this already.
I want markers/icons like already watched and on watchlist next to every title in all lists of any actor etc. As of now these lists are double-columned with title on the left and year to the right. I envision 2 tiny, new columns to the left of the titles with these icons. Alternatively you could place those icons to the right of the titles without creating new columns. Whatever is more pleasing to the eye. (2 pictures down i gave you an example)

There are other websites out there, which take the data from imdb and provide the feature i'm talking about. The following picture shows an example. The site doesn't have lists or tables; they chose a poster format, where the icons are below each title. This could be a useful alternative to watch lists for imdb as well.


I love the imdb feature, which splits up the directorial etc activities to movies, series, documentaries etc. How about for each category a progress summary. I made an example:

Here i marked two titles with a "D" for done and one title with a "W" for watchlist. You can substitute these letters with stylish icons as well. Next to the heading i added the progress. We currently got 30 movie credits for this actress. "2/30" i have watched already. This adds up to about "6 %" watched. From the remaining 28 titles, i got one on my watchlist.
You can argue about the counting method, because you can also have already watched titles on the watchlist, if you want to rewatch them. I'm not sure either, what would be best, but i think i'd kinda like to see the number 28 go down with every new title that i watch. Same as i like to see the watch percentage go up.

A few other subfeatures worth considering are:

• to select single episodes or seasons from tv series to mark them as watched
• to give a specific watch date, when marking a title as watched (for example "right now" for just watched, "release date" for watched close to release of the title and "specific date", where i can choose a specific date in history or a year, where i think i might have watched this
• give me timeline of all my consumed movies etc (sorted by watch date, release date etc)
• when i mark a title on the watchlist as watched, delete it from watchlist (this might already be in place; haven't tested that yet)
• let me mark future movies, tv episodes on my watchlist (and maybe give me a notification when they are out)
• publish the watched list/watchlist on imdb for others to see
• add up the runtime of all watched movies, tv series etc (if you are a movie buff, you can easily end up with a few hundred days of watchtime; i love those numbers, lol)
  

The reason why i want this on imdb is that i love imdb. I use it for years. But now that i have found these other sites which provide this watch feature (that i want for ages and have realized poorly on my own), i rarely browse through imdb anymore, because i pretty much have the same lists on the other sites, where i mark stuff watched on a daily basis.
But imdb is the bigger site. It has a better backbone/performance and the data is more accurate/up to date.
I've used the other site now for 2 weeks and have recorded a few hundred movie titles and tv series as watched. I still haven't reached the point of no return to come back to imdb, but i guess if i mark a few thousand movies as watched on another site, i wouldn't want to do that "work" on imdb again and you might lose me for good. I'd like to only use one movie site :(

Is there any chance, that such a feature might be added to imdb as well?

Thank you and kind regards,
Erika
