Problem Statement

When using plan mode, I'd like an option to suppress the plan output in the terminal while still having Claude Code generate and follow plans.

Use Case Example

I use an external tool to view plans and only want to see Claude's responses in the terminal. Currently there's no way to hide the plan display, so time is wasted scrolling and hunting for the response I'm interested in.
