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.
What language are you guys writing Dev Tools? I'd love to be able to help out, but I'm not too great with C++?
