I think there's a plus and a minus to the class navigation features of IDEs. Undoubtedly they make it faster to find your way through a thread of code, helping you to avoid breaking concentration and flow. However, I also observe that many of my colleagues who exclusively use an IDE never actually learn the structure of the codebase. Starting in on a bug or a task from scratch, they don't have the instinctive knowledge of what file & method to go to straight away to start working on the problem which I feel like I've gained via time spent navigating the codebase more manually.
