FR: allow verbose option with GUI

[iagogv3]

Hi!

Thanks for the great app!

I would like to suggest a minor option which is, when executing the app through the GUI, it would print among the CLI messages one which would show the command line batch mode instruction (with *** instead of passwords) producing an equivalent result to the one obtained through the GUI arguments specified.

Main reason fo this: learning to use the different command line options beyond the examples specified.

Thank you!
