Excellent for tracking changes in VBA code.
Over the last couple of weeks I have used this app extensively. I am developing a fairly complitcated Excel VBA program. Using this app I am able to compare different versions of the bas modules. Several updates I made in my code did not work so I had to backtrack. I found differences betwen new and old versions that I never would have found by eye. The code is very easy to use and very intuitive with its color scheme.
