Add flag to disable logging or skip user input

I am writing a script that uses this, and it requires the user to press y/n and then hit enter because it creates a log and requests whether that log should be deleted or not at the end.

I shouldn't have to make the user edit their config or have my script automatically overwrite the config just to suppress that output.

Alternatively: Allow us to pass a config file to overwrite the default for one run. That's even better because it allows me to make the other change I'd like to - changing how file names are formatted.
