Currently the ordering of a diff seems to be alphabetical based on file paths. However, if our source files are in a folder that starts with "XYZ", then we might also have unit tests in a folder called "Tests", and thus in all our diffs the first thing to appear are changes to the unit tests. A diff might be more focused if the first thing a user sees were changes to source code in "XYZ" rather than unit tests in "Tests".
