In my opinion, the ideal state of a poster is that of an unblemished one. The more markers visible on a given screen, the more visual clutter.
Which is better, a marker for watched or unwatched, comes with another question: Which majority is more common? For me, it’s drastically in favor of watched media. Thanks to this change, a majority of my posters are now marked with an intrusive green checkmark.
I too would prefer an option to switch this state.
That’s why there should be a simple option in the settings. Show a badge for watched, for unwatched, or don’t show at all.
They already tried this with an old preview version of the new Modern layout, and I said the same thing.
I agree with you on the preferred state. The watched green checkmark doesn’t make much sense. Why would I want to see that on every single poster in my collection? An unwatched badge at least lets me know at a glance what content is new to me and it’s functional.
