Not sure about floating windows (I don't like them much personally, so that might be why), but I've been toying with the idea of building a UI for a web-based database that would allow you to drag links onto the sides of "internal windows" or alt-click links to intelligently create a new window somewhere. Kind of like a tiling window manager, but just for one site. Since the devs would control all the UI code, they'd make sure it scales to very small sizes.

The idea was to make the common action of "opening multiple links from a list in new tabs" better, where tabs are too large containers and OS windows are often unwieldy. If you wanted to look at one of the results further in a bigger window, you could then pop it out into a new tab (again, kind of like tiling WMs with desktops).
