Is it possible to add an option for neutral faces? I don't really like either of the patches' expressions (there'd be nuance here to explain why but for the sake of this post I'll zip it) but I don't know if polls can be edited.
I didn't find an option to change the poll.
But in any case, to add neutral faces - you need to make a new animation after all. Here we work with the set that is/was in the game.
I think asking to improve the faces to neutral, this is a separate topic, and it should be opened as a separate topic then.
