Organizing the project navigator

You may notice that these new classes have cluttered the project navigator. This is a good time to clean up the navigator. Right-click the project in the project navigator and select Sort by Type, as shown in this screenshot:

Your project navigator will segment itself by file type and sort into alphabetical order. This makes it much easier to find files as you need them.
