Apple Newton had a way to drag/copy things around, a visual clipboard of sorts. They used a stilus, so it's similar. You drag an object to a side of the screen, where it turns into a visible but small handle and stucks. I think it could stay there any time and you could have several objects arranged this way. Then you can go anyplace, including a different application. Once you're in the right place, you could drag an object back and put it where you wanted to put it.
