Another QoL feature I would *greatly* enjoy in Multiplayer is the ability to disable Reaction-Popups from other players.
Most of the time I have no issue, since it's usually not on my turn anyway, but there are times where it gets really annoying.
But if someone, or even multiple people have used a parasite to get the "Turn your hit into a crit" feature, then every single attack they land will have that popup. And when you play with 4 people, and you all take a simultaneous turn, you suddenly get interrupted in your turn each time a party member lands an attack. The amount of times this has happened so far is painful, and we're only just done with the first part of the game.
It's not a big issue at all, and the worst it does is annoy me, but for QoL it would be amazing to be able to turn these popups off.
