Implement marker to see fork point

Feature request for product/service

Cursor IDE

Describe the request

we have ability to fork chats. It would be nice to have a marker which will show the point where the fork was started. The original chat also should have a marker which will point to “child” thread.
Not often required, but nice to have. Sometimes this helps.

Operating System (if it applies)

MacOS

Hey Eugen, thanks for the suggestion. This is an interesting idea! If it gets more traction and we see this come up a lot, it could be interesting to pursue further.
