Feature: Add fullscreen mode to Codex

What variant of Codex are you using?

CLI

What feature would you like to see?

Hi everyone!

I'm now asking for a fullscreen display to be added. Claude Code added this feature in version 2.1.226. Since Claude Code isn't open-source, I tried to recreate their fullscreen display: It worked! I even added a non-native terminal scrollbar. If you want to take a look and see if it would make sense to add it to the Codex: https://github.com/Hermenics/deepseek-code

(The repository isn't just the fullscreen display - it's a complete CLI for DeepSeek. I'm not promoting it in any way.)
