Stefan showed me a way to manage of a lot of code. More specifically, Xcode or Eclipse with the former being only for and required on Macs. What this handy bit of software does is to sort through all of your programs that you're writing.
The most useful thing I've found so far is that if you right click on a function you've defined, you can have the program show you where it is defined. Neat! I always looked down on Xcode when I programmed earlier because it was the default for opening program files, but I see it has more use than just making apps and being slow!
