Terminals don’t suit this approach of trying to get an overview of what a program does. Personally I find trying to get an overview of a complex program/concept/project/anything quite taxing and laborious. Terminals are a welcome relief from this issue. They are precisely as complicated as they need to be for a given task. A GUI will never have this property.
