Feature request: collapse resolved question/reasoning history in transcript view

Summary

When working across multiple open Claude Code conversations, it's hard to tell at a glance which ones still need input vs. are done. Specifically:

• Once an AskUserQuestion-style prompt is answered, the question/context around it stays fully expanded in the transcript — it would be nice if it collapsed into a toggle (click to expand for context) once resolved.
• More generally, the reasoning/tool-call trail is often useful to have available, but clutters the view when flipping between several concurrent conversations just to check "what's this one waiting on."

Suggested behavior

• Resolved questions/answered prompts collapse by default into a one-line summary + expand toggle.
• Optionally, a persistent one-line "status" indicator per conversation (waiting on you / in progress / done) visible without opening the full transcript, to make scanning multiple open sessions faster.

Context

Came up while using Claude Code across ~6 concurrent conversations for different tasks — the verbosity of the live transcript made it hard to quickly triage which conversations needed a response.
