UI Branch Management missing

What version of the Codex App are you using (From “About Codex” dialog)?

26.623.41415

What subscription do you have?

Pro 20x

What platform is your computer?

Darwin 25.5.0 arm64 arm

What issue are you seeing?

The new Codex UI no longer exposes the branch/worktree controls that were previously available in the thread header. I can see a Sources dropdown, but the old branch controls like Create branch here, Hand off, or an obvious current-branch/switch-branch control are gone.

What steps can reproduce the bug?

Steps to Reproduce:
Open an existing Codex thread using the new UI.
Look at the thread header / top toolbar.
Try to find the current branch or switch branches from the UI.
Open the Sources dropdown.

What is the expected behavior?

Expected Result:
There should be a visible way to:
see the current branch/worktree,
switch branches,
create a branch from the current worktree,
hand off or move the thread to a normal branch.
