Problem or use case

I cant get the context from a chat if my limits is hit.

Proposed solution

A new thread to markdown button which gives a .md file for the whole chat

Why this matters

Well you can just copy the whole thread but this way it will be easier plus we can extract the info which is not necessary

Smallest useful scope

Just copy paste the thread

I have done some testing, not for whole thread, but for "last message" here #1455
You can take a look and maybe it's easy to expand into a "copy thread".

I made the whole feature but cant pull the fucking requests. Look here is a video showing how it works

+1 here, missing the feature dearly. Came here for that. Unfortunately the project does not accept PRs.

Use-case / user-story 1: a trusted and quick compact and handoff

Manual handover based on visible transcript (User vs Assistant messages) as "Copy to Markdown" is instantaneous; reasonably sized; Observable; Editable (can cut in the middle); And can be given away to another model (e.g. Codex Sol -> Fable).|

Use-case / user-story 2: handover of a discussion and results to colleagues, or attaching to a PR; saving for later, etc.
