Now you can see a view with the zoom scroller on the bottom right. Very useful to see images or videos on folders.
[robg adds: This is a variation on this older hint, which used a smart folder to display a narrow range of results with the slider; this method just opens it up to all files within a folder. Alternatively, as noted in the original hint, you could just opt to leave the View Options window open instead, as it contains a slider for icon size (as well as grid spacing).]
