I totally support this idea!
Right now, when sharing revenue, I have to manually split the earnings and send them to each team member myself.
If itch.io could handle that part automatically, it would make things so much easier.
This might be a bit niche, but in Japan, there used to be a platform called RPG Atsumaru that had exactly this kind of feature—it was called the “Collaborator Function.”
Sadly, the site no longer exists, but the feature worked just like what you’re proposing.
Personally, I wouldn’t mind if a small handling fee was taken from the split.
I really hope this gets implemented!
