Hi Psygorn, yes that is JavaScript code. it's not so easy to learn how to use this with MoI because there isn't currently a lot of documentation or tutorials written about this particular area. You mostly learn how to do it bey looking at the scripts for regular commands which you can find in the commands folder inside the app.

There is a little bit of information here though:
