OK, I searched but did not find this on the forums, but my search-fu is weak. I assume I'm one of seven Tiger users who are unaware of this feature. However, for the first time ever, I dragged a widget from the bar instead of clicking to launch it, and saw the icon morph into the widget (and back to the icon if I dragged it back before releasing the mouse). Has this always been there in Tiger? Is there anyone else who wasn't aware of it?
