I have recently changed from using Overlays to using Layers to present video side by side. This is because our operators can then view the resulting scene in the preview window. With Overlays the first time you see the scene is at the output. I can use SetMultiViewOverlay to assign a camera to a layer. But there is no way (that I have found) to later know what input/camera is assigned to that layer.

Feature request: add records in the XML doc that give what input is assigned to each layer for an input. Then this information will be exposed to a script.

Maybe I'm misunderstanding, but this already exists. The overlayed inputs are referenced with the "keys" in the overlay section of the inputs, see:

https://www.vmix.com/help29/DeveloperAPI.html

Code:
<input key="55cbe357-a801-4d54-8ff2-08ee68766fae" number="2" type="VirtualSet" title="LateNightNews" state="Paused" position="0" duration="0" muted="True" loop="False" selectedIndex="0">
LateNightNews
<overlay index="0" key="2fe8ff9d-e400-4504-85ab-df7c17a1edd4"/>
<overlay index="1" key="20e4ee9a-05cc-4f58-bb69-cd179e1c1958"/>
<overlay index="2" key="94b88db0-c5cd-49d8-98a2-27d83d4bf3fe"/>
</input>
