Thanks for your proposal. [:)]
I don't think it's crap, it's just that it probably won't happen before a very long time, simply because you can make most of these adjustments in other 3D software before importing furniture, and many other features are more important / awaited.
At the opposite, I tend to think that the current settings render objects too shiny very often, and wonder if I shouldn't reduce at least default shininess to a much lower value. But I should rather start inverting in Yafaray, shouldn't I?
