I know, there's some mixed feelings about the mechanics. The prior mechanics of directly trading animals was perceived pretty negative by quite some players in game and also resulted into the output of free nightmare fuel coming from the Witch upon trading animals. As you may remember, the blueprints were a random drop from trading so not guaranteed and were also only able to be traded once per day. This old mechanic also limited the recipes and items to only be traded for one item/animal at a time. I changed it up to be more simplified, with the animals still appearing in the tab, but instead of a random drop, you simply have to give her combinations of living animals, or more than one animal at a time. I altered the "crafting" animation to the "give" animation and edited the recipe descriptions to be literal quotes from the Witch to make it feel more like a trade.
All in all I don't think the old crafting method will return, but I will make sure to make our Witch feel like a NPC, rather than a crafting station.
