Feature Suggestion: A "thread map" to navigate back after going deep into a sub-topic

The problem:

When Claude gives a multi-point answer (say, 3 key points on a topic) and I dig deeper into point #1 by asking follow-up questions, I often go several messages deep into that one thread. By the time I'm done, I've lost track of points #2 and #3 — and the only way back is to scroll all the way up, re-read, and re-orient myself. In long or technical conversations this gets frustrating fast.

The suggestion:

Some kind of dynamic, auto-updating outline or "thread map" that sits alongside the conversation — built live as Claude and I talk. Rough idea of how it could work:

• When Claude lays out multiple points/branches, they get logged as anchors in this outline.
• If I go deep into one branch, the outline stays visible (sidebar, collapsible panel, or a "jump back to overview" button).
• I can click any earlier point and jump straight back to it — like a breadcrumb trail or table of contents for the conversation itself, rather than for a single document.

Why it'd help:

• Long conversations (research, learning, debugging, planning) naturally branch. Right now the only "memory aid" is manual scrolling.
• It's different from chat history/search — this is about navigating within one active conversation, not finding a past one.
• Even something simple, like Claude periodically restating "we branched from: [X, Y, Z] — you're currently in Y" would help a lot.

Curious if others run into this same problem, and whether the Anthropic team has considered something like this.
