Visually identify branch point

There is no way to tell where a branch was made in a thread. It is difficult to review the context of a branched chat when you have a long thread. (or multiple, verbose prompts and/or responses)

Imagine you have a chat with 10 long responses. Then you create a branch which has another 5 long responses. I need to get back to the start of the branch so I can look at the prompts and figure out how I want to tweak them.

Options:

• Thick line across the chat that makes an easy to find visual delimiter

• Collapse all chats before the branch point
