Other input and control forms
More than a pull request, I would like your opinion. I found this tool not entirely matching my workflow. I would rather call this tool from another one and pass JSON rather than so many input files. JSON is not practical for the command line, yet if it comes from another program there is no issue.
I have avoided making big changes to keep code compatibility. In this case I only have a request for the extended public keys at the account level, instead of the payment key level. I want to derive the keys in my tool and not every single time with this tool and generate a new file every time. Consequently when witnessing a transaction, I want to pass from my program a large JSON instead of individually specify each signing key file.
What do you think?
