would be great to have a logging option that only showed you eg. state changes and vm output, and only displayed blocks with transactions in them. Something like log_dev = true in the config.

I'm not sure if the logger package supports having multiple loggers at once with different log levels - this would be the nicest way to do it. if log_dev == true we'd silence the main one and set the dev one fully on.

alternatively, we could just use fmt.Println in the critical locations if log_dev == true

Thoughts?
