Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I use the Codex plugin for Cursor. I have always had it pinned in my left sidebar, but after updating today to 3.10.11 it has disappeared from the list of things to show in that view.

Using Cmd+Shift+P > Codex: Open Codex Sidebar doesn’t bring it back into the view

View: Open View doesn’t list Codex in the available Sidebar options. It does appear in the Explorer section, but using that means it’s squashed under my file explorer panel rather than full height.

Steps to Reproduce

Using Cmd+Shift+P > Codex: Open Codex Sidebar doesn’t bring it back into the view

Does this stop you from using Cursor

No - Cursor works, but with this issue

I’m seeing the same issue on Cursor 3.10.11.

Codex no longer appears as its own sidebar view. Codex: Open Codex Sidebar does not restore it, and it only shows up under Explorer.

Relevant log line from Cursor:

[openai.chatgpt]: View container ‘codexSecondaryViewContainer’ does not exist and all views registered to it will be added to ‘Explorer’.

Hey everybody,

Thanks for the reports. I can reproduce this on 3.10, while it works on 3.9 (you can still download 3.9 from Cursor · Download). I’ve flagged this for the team!
