SlashDot pointed me to one of the most innovative UI ideas I’ve seen in a long time, and one that solves a real issue. Fold n’ Drop is an attempt to better address the issue of how to drag a file to a window that’s behind a bunch of other windows. Watch the video. Very cool.
Fold n’ Drop is a new interaction technique for seamlessly dragging and dropping between overlapping windows. It allows you to fold windows while dragging objects […]. Although it is still a research prototype, having it integrated into most popular window managers is technically conceivable.
There’s already a third-party implementation for you Windows folks (I didn’t try it, though, so caveat downloader). I hope this will get some buzz and become an available feature in Linux window managers shortly.
