Enhancing the Preview function in the client

Last time somebody changed something in the code of the client was about 3 years ago. I would see this project as not very alive any more. Many of us builds their own clients, using various programming langages. Maybe it would be an idea to think about that, or about a new official client.

By the way: I started a discussion about that also about 3 years ago here. @Andrea had started to develop something, but it seemed not to be able to become the new official client yet.
