Setting Up Parallel Development Environments with Codex

Here's a quick video showing you how I've set up my local dev environment to do a lot of parallel work at the same time. I'm really enjoying the Codex app. Over the past year I've been 100% in the TUI/CLI but I think the GUI form factor is really starting to work and I’m enjoying Codex a lot. Also, I've been using gpt-5.3-codex on extra high the whole day.
