Open files directly in Codex app

What variant of Codex are you using?

Codex Windows app

What feature would you like to see?

Please add an option to open files directly inside the Codex app itself.

Right now, the "open file" / run-action dropdown only lets me choose external applications such as VS Code, Visual Studio, Cursor, Antigravity, GitHub Desktop, File Explorer, Terminal, or Git Bash.

I would like that dropdown to also include Codex itself, so I can open and inspect the file without leaving the app.

This matters for two reasons:

1. Less context switching

I would prefer to stay inside Codex instead of constantly jumping to another application just to inspect a file.

1. Line-number fidelity

Codex often shows a file path together with a specific line number. If I open the file in another application, it does not reliably preserve the same line/position, which makes navigation inconvenient and slows down review.

Requested behavior

Add a built-in "Open in Codex" option to the existing dropdown/menu.

Ideal behavior

• Open the selected file inside Codex
• Jump directly to the referenced line number, if one was provided
• Keep me in the same app and same workflow context

This would make file inspection much smoother, especially during review, debugging, and follow-up navigation from Codex-generated file references.

Additional information

The current external-app dropdown is useful, but it feels incomplete without a way to open the file in Codex itself.

A built-in viewer/editor target would be much more convenient than switching to another tool, especially when Codex already knows exactly which file and line it wants to show.
