You know that, in the Layers Setting window, each column header is a button.
In ArchiCAD 8.0 I saw an empty button on the right end, that seemed to do nothing. In AC 8.1 there is a funnel icon on it, and it's use is simple and clear: show ONLY the layers with the same extension of the one currently selected.
I think this in not in the manuals.
