Hi Jeff, Thanks for your suggestion. I ended up doing it slightly different (see my response to Thad Humphries).
However, I’ll keep your idea in mind because the ability to both include a standard configuration in the app and also optionally modifying this configuration via an external config file seems interesting. I can easily see that we might want to do this in the future.
