So, are you saying that there is an option to sell the items?

No there isn't at the moment. But if it was added, it should be done in a way that makes it sell without having to micromanage the last object to sell it too.

If you use "make many" when cooking and then queue up another action afterwards, the Sim will finish cooking the current dish before moving onto the next action. Thats how I feel it should also work for the crafting stations.

Well, doesn't it do that with crafting? What gets interrupted? I remember Make Many working that way for all the craft stations--items go in inventory.

Also, I think in a vanilla game, Make Many doesn't work right for anything going in the oven. Like for example making pie--as soon as it goes in the oven, the sim walks away and starts a new batch, and if you aren't paying attention/fast enough, the old one gets burned. I have Squinge's Don't Walk Away while Cooking and that prevents that behavior.
