I would like to propose that we increase the verbosity of two operations:
1) When a parameter file is parsed, I would like several pieces of information output via the "INFO" level of the logging handler. This would be the current simulation time, the dimensions of the domain, and any cosmological parameters. 2) When print_stats is called in the hierarchy, I would like to include all of the cosmological parameters.
The reason I'm bringing this up rather than just changing it is that in the past yt has (rightly) been accused of being too verbose (in fact, it was one of the first things Jeff said to me the first time we met to talk about yt!) and I don't want to increase that unnecessarily. But, I feel strongly that as we move into more codes we need to be more upfront about what yt thinks of a given simulation output. I think that this will also help ensure that errors are avoided.
