Feature request: Add a remote visual preview/control mode for Codex mobile

Hi Codex team,

I would like to suggest adding a remote visual preview / remote control mode to Codex mobile.

Right now, Codex is very useful for editing, refactoring, and implementing changes, but mobile users still have a major gap when the task requires visual validation. For example, when working on UI, animations, layout, web apps, iOS apps, or any project where the final result must be visually inspected, the user often needs to be at a desktop computer to open the running app, test interactions, and verify the result.

A remote desktop-like feature inside Codex mobile would make this workflow much stronger. The idea is not necessarily to expose a full unrestricted desktop by default, but to provide a safe, session-based way for the user to view and interact with the development environment, preview window, simulator, browser, or running app directly from Codex mobile.

This would be especially useful when the user is temporarily away from their computer and only has an iPad or phone. In that situation, the user could still review UI changes, interact with the app, test flows, check animations, approve Codex changes, and continue development without waiting until they return to their desktop.

Some benefits:

• Better UI and visual QA: users can directly inspect layout, spacing, colors, animations, responsiveness, and visual regressions.
• Better mobile productivity: users with only an iPad or phone can still meaningfully continue development and review Codex work.
• Faster approval loop: instead of asking Codex to describe visual results, the user can see and test the actual running app.
• Better support for frontend, iOS, Android, game, and design-heavy projects.
• Fewer incorrect merges: users can verify visual behavior before accepting or merging changes.
• Stronger Codex mobile experience: mobile would become more than a code review interface; it would support real development validation.
• Better collaboration with Codex agents: users can let Codex implement changes, then immediately open the preview remotely and provide visual feedback.
• Useful for temporary travel, classes, meetings, commuting, or any situation where the user cannot access their main development machine.

Possible implementation ideas:

• A secure temporary remote preview session tied to a Codex workspace.
• Read-only visual preview by default, with optional user-enabled control mode.
• Ability to open a browser preview, simulator, local app preview, or selected window.
• Touch-friendly controls for iPad and phones.
• Clear permission boundaries, session expiration, and user confirmation before enabling control.
• Optional screenshot/recording tools so users can give Codex precise visual feedback.

I think this would be a very valuable feature for Codex mobile, especially for users who rely on Codex for UI-heavy projects and need to visually inspect and approve work while away from a desktop.
