Corkboard

Corkboard is to copy and paste what Exposé is to the minimize button. It lets you manage your data and works-in-progress in a new and intuitive way, by working alongside your clipboard—the place things go when you copy or paste them—to hold more data and show you exactly what's going on.

You can drag-and-drop data to Corkboard, where it will be kept for safekeeping between reboots, crashes, quits, and saves. When you need to use the data again, just drag it back out to the program that needs it. It's fast, simple, and easy. Corkboard keeps track of everything you copy to the clipboard. If you copy over what was there, it might be forgotten, but it's not gone. To keep it permanently, drag or paste it into Corkboard from almost any application. Even if Corkboard doesn't know how to show that data, it'll still hold onto it for you. Never again do you need to risk losing it all.
