If you're interested I did map out the entire API surface for MoI 5 over the xmas holidays and created comprehensive type definitions for all. I'm developing a script editor plugin which includes type checking and live execution, here's a quick preview: https://www.youtube.com/watch?v=Ru8p8kA54Mw

More to come. If this is something that interests you, you can reach me via email at turbo@code.tc (I don't want to hijack this thread for this project), would love to learn more about your use cases for scripting MoI.

(Though I wish I wasn't spending 60% of the time on this project fighting the ancient webkit version.)
