Note that Emacs' window splitting ability doesn't stop at splitting the editor in two. You can recursively keep splitting as much as you want: when navigating complex code bases it has helped me in the past to have it split into four sections. More splits than that made the displayed sections too small for my taste, and even if you have all those splits right in front of you I personally felt that I had a harder time keeping track of where to look.
