self.nGrokUrl

In the trape.py code, there's a line that reads self.nGrokUrl = ' '

Is that where a user could insert a reserved ngrok domain?

What else would be required for persistence? (i.e. - setting up trape and then having it work every time you load the program)

Start with the self.nGrokUrl assignment in trape.py and trace how that value is used when the program loads. Determine what configuration or persistence behavior is required for a reserved ngrok domain; done means the setup works consistently across subsequent program loads and the behavior is documented.
