Support Custom Action Buttons/Commands in Status Bar (similar to VS Code Commandbar)

What variant of Codex are you using?

App

What feature would you like to see?

Currently, the Codex App UI is entirely hardcoded. Users cannot extend the graphical interface to map their frequent local workflows. For instance, if I want a quick-access button in the status bar (bottom-right corner) to perform a local action (e.g., launching an external tool, triggering a custom deploy script, or opening a specific path), there is no way to achieve this.

I would like Codex App to support user-defined custom UI elements in the status bar or toolbars, similar to how the vscode-commandbar extension works in Visual Studio Code.It would be amazing if users could define a simple configuration file (e.g., .codex/commandbar.json or within config.toml) to inject custom buttons into the UI

{
  "commands": [
    {
      "text": "Unit Test",
      "command": "npm run test"
    },
    {
      "text": "Deploy",
      "command": "bash ./scripts/deploy.sh"
    },
  ]
}

Start by locating the Codex App status-bar or toolbar entry points and the existing config.toml handling. Compare the requested .codex/commandbar.json shape with current configuration conventions, then determine the UI, command-execution, and safety behavior required; done means documented custom buttons can reliably trigger configured local commands.
