I just recently switched from Eclipse and JDeveloper to IntelliJ Idea, i have heard a lot of fellow programmers praise the paid version as the best IDE available, but as far as i have been able to work with it (a couple of days now) i haven't found that feeling yet, so i'm obviously missing something, or haven't worked with the IDE enough, thus my question is:
What are the most powerful features of IntelliJ Idea?
