In data retrieval systems, there are typically two ways you find things: searching and browsing. What you're describing are the facilities that modern IDEs and editors provide to support searching. Those are great, and like you, I use those search facilities to jump directly to a specific point of interest a lot of the time when I'm developing. However, searching is useful only if you already know what you want to search for. If you're trying to explore the overall structure of a large program, having the files (and the contents within those files) organised systematically still makes browsing easier.
