GUI PSDs can be quite useful for designers. For most of the people to get inspired and see how other have created certain buttons or User Interface elements and for some people to actually use in projects, if a commercial license is available, of course. In any case, a comprehensive list that would compile the best GUI PSD files is a useful thing and so this article came to life. At first there were over 100 PSD files but in the end only about 70 remained. It’s still a large number but I’ve kept only the ones that can be used.
