Good point, I was surprised it didn't work like that. Guess it's one of those little things. Personally, I think that console could do some work. Chrome console is top notch, and there is too much noise in FF version, with CSS and other stuff.
FWIW, you have pretty fine grained control over what appears in the console (CSS, JS, Logs, etc.) as well as the level of logging (Error, Warning, Log)... see the dropdown buttons at the top of the console tab :)
EDIT: Another thing, there needs to be a font shape difference between input and output. Basically, you should be able to tell if something is input or output without looking into the arrows to the side.
