What variant of Codex are you using?
Codex CLI
What feature would you like to see?
Diffs are easier to read when the sections of the line that are changed are highlighted, a la delta or the standard way diffs are displayed on GitHub. If that could be done when Codex CLI is displaying diffs to the use during edits, it would make noticing problems or concerns easier.
In case what I mean isn't obvious, this is the diff style in question (as shown on delta's examples page, delta itself is at https://github.com/dandavison/delta but I'm not suggesting you use delta itself.)

@etraut-openai Would it help if I just implemented the feature and submitted a pull request? (And yes, I still feel it is needed; it's a small but significant quality of life improvement.)
