This is an auto-generated question from the MPS Slack community:
MPS has a startup option that will make MPS show a ‘developers’ menu, where you can e.g. see all action ID’s and much other internal information. I have used this before, but have forgotten how this option is called. I though it was something like `-Dinternal=true`, or `-Dmps.internal=true` but these doesn’t work. Does anyone know this option and how it is called?
