Hi Łukasz, Can you please expand what you mean? We already added Logger.put_process_level/2, which applies only to the current process at the moment. So it seems there is a pitfall we may need to document? I believe a process cannot override the general log level, is that correct? In other words, it can only be used to have a more restricted one.
