This is awesome, but pretty sure the reason vgen doesn’t have this is to kill any competition between artist as much as possible and to keep prices high.
When you can easily compare artist and their prices there’s usually a clear choice on who will get more commissions.
Obscuring the price of art as much as possible makes comparisons a lot harder to make between artist when you’re a customer, resulting in incredibly variable prices compared to the art that they produce.
This will result in prices being higher than usual since artist will usually get a commission without having to price their art competitively, since it’s so hard for customers to compare prices between artist without having to go through all this effort.
