Why Are Some Features Available in the Code Editor but Not in the Agent Window?

I noticed that some features are available inside the code editor, but not in the agent window, such as /best-of-n and others.

This creates an inconsistent experience, because users have to keep switching between the code editor and the agent window just to access certain features.

It would be much better to unify the experience so the same tools and features are available in both places, allowing users to continue working smoothly whether they are in the editor or the agent window without constant context switching.
