Feature Request: Bring Back the File Explorer Button in Codex

Hi OpenAI team, I’m currently using Codex, and I noticed that the file explorer button recently disappeared from the interface. This was a very important part of my workflow. When working on a project, I often need to quickly inspect the project structure, open files, check where generated or edited files are located, and understand the codebase visually. Without the file explorer button, navigating the workspace feels much harder and slower, especially as projects grow larger. For coding workflows, a visible file explorer is not just a convenience feature. It is essential for quickly understanding the project structure, checking which files Codex created or modified, opening documentation and source files without relying only on commands, helping new users feel oriented inside the workspace, and managing larger projects with many folders and files. Please consider bringing back the file explorer button, or adding an equivalent always-accessible project/files panel in Codex. This would significantly improve usability and make Codex much more practical for real project work. Thank you!
