Feature request: Private/hidden projects in Codex sidebar

What variant of Codex are you using?

App

What feature would you like to see?

I’d like Codex to support private or hidden projects/threads in the left sidebar.

Use case:
When screen sharing or when someone can see my computer, project and thread names in the left panel may reveal private client, company, or personal information.

Suggested behavior:

• Allow marking a project/thread as private or hidden.
• Hide or blur private project/thread names in the sidebar by default.
• Require unlock via password, Touch ID/Face ID, local PIN, or account re-authentication.
• Allow restoring/unhiding later.
• Do not delete or move local files.
• Optional: provide a “presentation/screen share mode” that hides sensitive sidebar names.
