Prompt history viewer: dedicated screen to browse/search past inputs

Feature Request

A dedicated screen or panel to browse and search through prior user prompts in the current session, separate from the full conversation scrollback.

Current Behavior

• Up/Down arrows cycle through prompt history one-by-one
• Ctrl+R does reverse text search
• Full conversation is in terminal scrollback, but prompts are interleaved with (often lengthy) responses

Requested Behavior

A viewer (e.g., triggered by a keyboard shortcut or slash command like /history) that shows only the user's prompts in a scrollable list, with:

• Prompt text (truncated to first line or N chars)
• Timestamp or relative position
• Ability to select and re-use a prompt
• Optional text search/filter

Motivation

In long sessions (especially multi-hour coding sessions with many tool calls), the conversation can be thousands of lines. Finding a specific earlier prompt requires scrolling through tool output, code blocks, and agent results. The arrow-key cycling works for recent prompts but is impractical for prompts from early in the session.

This is particularly useful for:

• Re-running a complex prompt that worked well
• Remembering what you asked 2 hours ago after context has shifted
• Auditing what instructions were given during a long autonomous session
