Hello !
It would be nice to improve the “friends” viewing interactions with a “viewed together” category.
For example, having the possibility of a “watch with someone” button to synchronise progress when my friends come to my house or vice versa.
In the same logic when we go to the cinema, only one person marks as “seen” and the others can go to their list and mark as “watched together” in order to synchronise the times as well.
In the end we can see a history of everything we have seen together.
