What variant of Codex are you using?

App

What feature would you like to see?

Please make the Codex App file tree/sidebar resizable, or otherwise provide a way to see full file and folder names in the file tree.

Right now, on macOS, the file tree/sidebar is too narrow for some project structures. Longer file and folder names are truncated, and I cannot find a way to expand the sidebar. Hovering near the sidebar edge does not change the cursor, and dragging does not resize it.

This makes it hard to distinguish files in projects with longer names, nested directories, or similarly named files.

A few possible fixes would help:

  • Allow the file tree/sidebar width to be resized by dragging.
  • Persist the chosen sidebar width across app launches.
  • Show full filenames/paths on hover.
  • Add a wider sidebar mode or compact/full path display option.

I searched for existing issues before filing. I found related but not duplicate issues:

  • #16669: adjustable chat content width in Codex App, but this is about chat body width, not the file tree/sidebar.
  • #8585: truncated file paths when manually adding context, but that is for a different UI and is closed.
  • #17213 and #18570: sidebar width/responsiveness issues in the VS Code extension, not the Codex Desktop App.

I could not find an existing issue specifically about the Codex App file tree/sidebar being too narrow or non-resizable.

TL;DR

The most likely fix is to implement a resizable file tree/sidebar in the Codex App, allowing users to adjust the width to display full file and folder names.

Guidance

  • Consider adding a drag-to-resize functionality to the file tree/sidebar, enabling users to adjust the width according to their needs.
  • Implementing a hover effect to display full filenames/paths could be a temporary workaround, providing users with a way to view complete file information without resizing the sidebar.
  • Reviewing related issues, such as #16669, may provide insight into how to approach the implementation of a resizable sidebar.
  • Adding a setting to persist the chosen sidebar width across app launches would enhance the user experience, ensuring that the preferred width is retained.

Example

No code example is provided, as the issue does not contain specific implementation details.

Notes

The solution may require modifications to the Codex App's UI and layout management, which could have implications for the overall user interface and user experience.

Recommendation

Apply a workaround, such as displaying full filenames/paths on hover, until a permanent solution, like a resizable file tree/sidebar, can be implemented. This would provide an immediate improvement to the user experience while a more comprehensive fix is developed.
