Track code changes

Wordpress has a feature where you can compare an article with the one in history, it will show what changes are made and differences.

It would be great to cs-cart to view custom changes in the code. It will be helpful to view against files in the repository and against updates.

Notice how well it can detect changes done in the middle of the test…

Would adding the ability to do a three-way diff with analysis detail down to the character level meet your needs?
