The new Codex icon is too similar to the ChatGPT Classic icon. As a user, I now find it harder to distinguish between the two applications at a glance, especially in the taskbar/dock or when switching between apps.
The previous Codex logo provided a much clearer visual distinction and made it immediately obvious which application I was using.
I would strongly prefer Codex to have a visually distinct icon again. Even a small but clearly recognizable difference would significantly improve usability and reduce confusion.
