What variant of Codex are you using?
MacOS App / CLI
What feature would you like to see?
In the app and CLI, would be nice if when done the planning phase it had an option to start a new thread and implement the plan so you start with just a spec file and fresh context, in both app and cli, just like how Claude Code does it.
Also should be an option to change the thinking level when starting plan, maybe like a three step:
1) Implement Plan
2) Cancel
1 > 1) Continue in thread
2) Implement plan in new thread
1/2 > Thinking level for implementation: XH/H/M/L

No, not a duplicate. This intends to maintain context forked into a new thread. I want to delete it.
Agreed this would be a great default behaviour.
By the time planning is done context for me is down to 50-60%. Having it either fork OR create an exec plan and then auto create a new thread would likely streamline implementation a lot.
