@JonB - Thanks for the interest.
I found a work flow that does include my INI files.
The curious thing is about this is by "select"-ing the full directory does include the INI file when opening in Pythonista. However, if you merely open the directory (and then view all of the individual files within the directory), the INI file(s) and in my case README is grey and un-selectable (if that is a word). If you then click "select all", you do not get the INI file(s) or README.
I do not quite understand why this would be the case, but there is an actual, reasonable path for me to move forward.
The integration took me a while to figure out, but only because it was so simple that I never considered it. Very nice integration work.
