[FEATURE] Conversation navigation. Jump between question-answer blocks.

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

I know I'd find it very useful - and others might as well - if one could navigation (keysroke combo; sidebar) from one question-answer pair to the next. Hunting backwards for my questions, in long conversations, it tedious and error-prone. I've switched to Windows Terminal and powershell precisely to get buffer search but this isn't as good as what I'm requesting.

Proposed Solution

This could show up as a keystroke combination or an indexed sidebar - or whatever better idea you have.

Better navigate long conversations - where understanding what's been transacted over time is all that much more useful.
