Not really. Just simplified it to (hopefully) make it easier to change the text and color, and not having to render out 30+ individual overlays.
@Comoving_Observer did you import the .json file under Scene Collection / Import?
Did a test here, and that imports all the overlay stuff, then you need to add A/V-sources.
Edit: My bad, forgot the stuff about the .json file in the guide. Adding that now. Sorry!
