Ill-advisedly, but for the record, teaching Grandmother to suck eggs, now: as always beware of getting what you think you want. One of our inherent limitations is that one can have only so many "prominent" items of any certain size (ignoring drop downs, links to continuations, etc) that one can place on a single-screen's worth of information... and the size that satisfies "A" as being prominent doesn't get that rating from "B."
