Hi all, I'm trying to figure out some concepts of the following site, specifically the drag to target function, if that is what's happening.

With the help of others here, I've learned how to drag windows around and fade, but I do not understand how they are "putting away" the file and making it fall into position. You can see that when you drag a window, mc I assume, into the bottom area, it resizes and falls into the correct position. Each windows stack one another after each other and even videos continue to play in that area.

Can someone explain what's happening here? I'd love to learn this trick.

Check it out.
