Adding a new item, put it at the top of the list instead of the bottom.

I don’t think there’s a wrong answer here, but putting them at the bottom makes sense. If we were being led in a session by an Implementor, then there would be a whiteboard and new items would be added below.

It simulates that experience so it gets my vote.

Also, adding to the top may inadvertently prioritize newer items over older ones and that’s not usually a sound method of attack unless something is both super urgent and important.
