I think they would look much nicer if they all had synchronized animations no matter when you put the material in.
Is it OCD? I have that with them, but i use Automate in SDV, making copper, iron and gold never stay the same rhythm, haha.
I often run out of the house or shed, but when busy in there, i'd like to have no annoyance through my OCD.
It's not that bad, my OCD, but it does make me lose concentration, sometimes staring at it to see them correct themselves, which they don't XD
But i do understand the suggestion, if it's about that.
My brains damaged makes me lose energy over it, too, and then i need a break earlier than i'd need otherwise.
Imagine playing a game to relax and have a few more intense moments (fighting monsters), then being annoyed over some automated machines, haha.
If it's worse for you, OP, then i understand your frustration.
