+1Yes, I like it too. Good idea.
Addition... If you have nothing selected, Clicking the "Home" key should go to the global origin, like when you first open up an empty project. (Maybe it already does that. But if it doesn't, it should.)
P.S.
That "Home key" sure is a nice feature. I can't believe how long it took me before I really discovered it, but when learning iClone I mostly used a couple of props and one avatar, all near the origin, so it didn't really do much. But yeah, once you have a full outdoor set, it's a lifesaver.
