Cool Safari feature

So I found out this cool Safari feature, probably I'm like the last person on Macrumors to find out about it but just to be sure I thought I'd share it:
If you have multiple tabs in one Safari Window you can just pull them of and create a seperate window from the tab! And like Exposé you can hold shift for slow motion. Of course you can also rearrange your tabs by just dragging them to another position.
