Feature request: Add a real code editor to Codex App like Cursor

What variant of Codex are you using?

Codex App

What feature would you like to see?

Codex is becoming much stronger, especially with image generation, browser workflows, Git review, and project automation. But one major missing piece is a real built-in code editor inside Codex App.

Many users want Codex to feel more like Cursor: file tree, tabs, syntax highlighting, manual code editing, live diffs, and real-time Git changes while the agent works.

Right now Codex is a powerful agent, but Cursor is still better as a live coding workspace. Adding a real editor would make Codex much closer to a complete AI IDE.

Please consider adding a real editor and real-time Git change visibility to Codex App.
