To the left of the close button in each widget is a diamond-looking button. I see that it kind of "pops" the window out of the layout and allows you to move the widget around some-what unaffecting the rest of the layout. But... I don't see the practical application or general use of this feature would be.

If someone uses this button/feature, can you tell me how you use it, or what you personally use it for?

Thanks!
