Yes, I have a json cfg file stored in the user app data folder.
I'm using DefaulTranslator so I don't know if I can change that folder path. Maybe there is a parameter I can send to the app when it starts. But I don't know if is available.
About Mac, I don't have one. I'm running it on a slow VM. I'm not sure where DefaulTranslator looks for translation on a Mac. Will be nice to know more about it.
