Dragging widgets off Dashboard

It's the "Feature of the week":

Widgets Wherever
Want to view a frequently used Dashboard widget alongside your current applications? Just open Dashboard, access the Widget Bar, then drag out the widget you want and hold down the F12 key. Dashboard disappears, leaving your standalone widget on screen. Close it by opening Dashboard again.

I think this is a great feature, just not so convenient that you have to drag it from the Widget Bar, not directly from the Dashboard screen. And when I wanted to use another widget that is not dragged to desktop, the widget on the desktop goes back to Dashboard and won't get back to Dashboard. I hope this can be fixed,
