In plan mode, the plan should stay visible in the context in terminal

1) have CLI form a plan -- possibly a long and detailed plan after careful investigation
2) either accept the plan, or offer more info (last option) to recreate plan.

The CLI continues as appropriate, but the plan text vanishes from the terminal scroll back buffer. I have Ctrl-t on, so I should see everything -- and most of what I do see (internal thinking) is far less interesting than the plan. I want to see the plan because

1) I can refer to it while its working without finding and opening the correct plan.md
2) it gives me confidence that it hasn't lost that valuable analysis - and hasn't lost my hopefully valuable commentary that I rejected the plan with
3) I can compare a second iteration of the plan it offers against the last one it presented.

I do not mind whether I have to have Ctrl-t on to see it, but I think it should not need that on, becuase this is "user focused" text.

What I don't know -- whether this is being hidden because it causes confusion to the agent because if its in the context? What I do know is the UX is not as good for it being hidden.

GitHub Copilot CLI 1.0.20 / Windows Terminal / inside Agency.

Tái hiện plan mode trong Windows Terminal, trước tiên với Ctrl-t được bật rồi sau đó được tắt, và quan sát những gì còn lại trong terminal scrollback khi CLI tiếp tục. Truy vết các entry point của phần hiển thị plan và xử lý context; được xem là hoàn tất khi plan vẫn khả dụng trong terminal trong lúc công việc tiếp tục và có thể so sánh các lần lặp plan liên tiếp.
