User Interface designer Eugenia Loli-Queru has written a thoughtful and well-illustrated article for OSNews where she discusses which parts of KDE are good and which ones could use some polishing. "What is a good User Interface? Well, in order to answer that, we will have to take into account that different people like different shapes, colors and functionality. This article is just my personal opinion, how I would like KDE to evolve in the future. I am sure that other users would like to see other, different types of evolution. However, we can't deny the fact that some basic rules of UI design should never be ignored." The developers have started a discussion (thread1, thread2) based on this article.
