Personally, I’m not a fan of the inline diffs that make you do homework to figure out what’s being added and what’s being removed.
For example, if you go to the Code – Commits page and click on the commit id for a given commit, as shown in the illustration below,
You’re taken to a page that shows the diffs as inline or unified for the file.
Fortunately, there’s a split button in the upper right hand corner that says Unified | Split.
Clicking on Split portion of the button will show the before and after changes side by side, which is just my personal preference.
