You may not "see" it in the sense of fixing UI bugs, but in the long run it saves you TONS of time. It ensures people code to an internal coding style document (you have one, right??) which makes code more readable and maintainable in the long run. It also, of course, can catch subtle bugs that may be compounded in time with new features. Together these saves tons of money and time in the long run. Don't be short-sighted.
