By default, SG logs to console at INFO.
Unfortunately, it currently appears to be ignoring the loggingLevel config option, and instead defaulting to the FINER level.

At least, that appears to be the case for some prompts, as shown in this image: https://i.imgur.com/rkAoh5V.png
(That screenshot was taken under the default config, which includes the INFO loggingLevel).

The blue ones should be INFO
the green ones should be CONFIG
the yellow ones should be FINE
the red ones should be FINER
