VS Code extension: Todo panel should resize with available space

What variant of Codex are you using?

IDE Extension / VS Code extension

What feature would you like to see?

I would like the Todo/task panel in the Codex VS Code extension to better use the available space when the session view is resized.

Currently, in the Codex session UI, the right side contains Todo/task information. However, when I make the Codex panel wider or resize the session view, the main chat area becomes larger, but the Todo/task panel itself does not expand to show more content.

This makes it inconvenient during longer coding sessions, especially when there are many todos or longer task descriptions. Even after giving the UI more space, the Todo area still feels constrained.

Expected behavior:

• The Todo/task panel should expand with the available space; or
• Users should be able to manually resize the Todo/task area relative to the chat area; or
• There could be an option to expand, pin, or pop out the Todo/task panel.

This would make it easier to monitor progress and understand the current plan during multi-step coding tasks.

Additional information

I searched existing issues and found some related VS Code extension layout issues, but I did not find one specifically about the Todo/task panel not expanding when the container is resized.

I attached a screenshot showing that resizing the Codex panel increases the chat area, but the Todo/task area does not make better use of the available space.
