Hi @Bojan Zivkovic ,
after working many years with System Center Orchestrator and .Net Script activities:
using VS Code or PowerShell Studio to write a code and just copy it to Details section
That's the way to do it. As far as I know there is no other option to get the nice and fancy things like "IntelliSense, format code, ....".
And I doubt there are plans in the near future to add these kind of features in SCORCH Runbook Designer.
