title: How find all unused classes in Intellij Idea?
body: <p>There is an inspection &quot;Unused declaration&quot; which can find all unused code in Intellij Idea. (see <a href="https://stackoverflow.com/questions/6587729/how-to-use-intellij-idea-to-find-all-unused-code">How to use IntelliJ IDEA to find all unused code?</a>)
  But I want to find all unused classes, <strong>not</strong> methods, variables etc. <strong>Only</strong> classes. (it is difficult to find only classes in 3000 result list). How I can do that?</p>
