Highlight movies and series based on status

Currently if you open up a list such as https://www.imdb.com/chart/toptv/ it doesn't immediately become clear that you watched a certain show unless you squint your eyes and look at the ratings given or the yellow icon for items on your Watchlist.

So now I'm using a userscript to give entries a color based on status:

🟩 = Watched/Rated

🟦 = Watchlist

🟥 = Dropped (Manually created list on https://www.imdb.com/profile/lists/)

That looks as followed on https://www.imdb.com/chart/toptv/:

Plus on Actor pages https://www.imdb.com/name/nm0050959/:

Userscript for those that are interested in trying it out:

This simple userscript offers a lot of clarity for me and I'm sure there are others that might find this kind of functionality useful on a website like IMDB. I wonder if there are any plans on adding something like this (or similar) that doesn't rely on 'hacky' userscripts that might break after IMDB changes something on the website.
