Sweet Home 3D doesn't log information because it's not a program running on server side.

Sorry I didn't mean if SH3D had server-side logging as in the Software-as-a-Service sense, I meant does SH3D have any logging capabilities in the client-side sense. Like in the log4j sense where the local program is logging what it is doing with various levels of verbosity to a default local system location i.e. /var/log on Linux. So no logs are leaving the machine.

This way an end-user could try to look at the logs or compare the logs across two platforms to provide insights towards getting to a root cause of an issue.
