Diff is Legit

Diff works as advertised. It highlights changes to lines of code inside my child-theme files as compared to the parent theme files.

Since I’m using a premium theme, I don’t have control over how the theme is written, so the @version detection feature will doubtfully be useful in this case since the parent theme isn’t using that on top of all their pages.

They are however using the @since tag for almost every function. That seems complicated to track. Diff is already highlighting the differences between lines of code, so @since might not be too useful either.
