Feature request: Orchestrator mode toggle for large Codex tasks

I submitted in-app feedback with this Feedback ID:

no-active-thread-019e6abf-c144-7a70-a7fa-a74f0373a908

Feature request:

Please add an "Orchestrator mode" or "Large task mode" toggle next to Plan mode and Pursue goal in Codex App.

The goal is to support large engineering tasks without polluting the main thread context.

When enabled, Codex should use the current thread as a coordinator:

• create an execution plan first

• split the task into independent subtasks

• identify dependencies and file ownership

• spawn subagents, side threads, worktrees, or cloud tasks where appropriate

• track task status

• keep raw logs, failed experiments, and test output inside worker threads

• return only concise summaries, blockers, decisions, and integration reports to the main thread

This would make Codex much better for large refactors, migrations, multi-module features, frontend/backend/database changes, and long-running engineering goals.

Expected UX:

• toggle: Orchestrator mode / Large task mode

• main thread shows a clean task board

• worker threads handle implementation details

• final output includes changed files, tests run, blockers, risks, and merge order
