Hi, just a simple event request: An event that fires when an assembler or furnace (and possibly boilers?) finishes crafting an item, to enable custom behaviour with the result.

This is already possible by cycling the entities every tick and checking if it has an item in the output, but I imagine an event for this occasion would be much more performant, and simplify code.

We specifically didn't make such an event because it would be a large performance drain on the game to call so often even when there isn't a single mod listening to it.

That makes sense! Thanks for the response.
