Codex app “Show all files” does not show hidden dotfiles

[tkozzer]

Problem

In the Codex desktop app, clicking Show all files in a project does not appear to show all hidden dotfiles. Since the control says "Show all files," I expected it to reveal files that are hidden by default, including dotfiles.

Steps to reproduce

1. Open a project in the Codex desktop app that contains hidden dotfiles, such as .env, .gitignore, .github/, .vscode/, or other files/directories whose names begin with ..
2. Open the project file browser.
3. Click Show all files.
4. Check whether the dotfiles are visible in the file list.

Actual behavior

Some dotfiles remain hidden even after clicking Show all files.

Expected behavior

There should be a way to view every file in the project, including dotfiles that are hidden by default. Either Show all files should include hidden dotfiles, or the app should provide a separate explicit option such as Show hidden files / Show dotfiles.

Why this matters

Dotfiles often contain important project configuration, development tooling, CI settings, and environment examples. When the app hides them even in an expanded file view, it makes it harder to inspect or reference the full project state from Codex.

Small wording correction / UI detail: the control is a dropdown with Changed files and All files options. I’m selecting All files, but hidden dotfiles still do not appear.

The screenshot shows the dropdown state:

• Changed files
• All files selected

Since the selected option says All files, I’d expect it to include dotfiles too, or for there to be a separate explicit Show hidden files / Show dotfiles option.
