While using the chat, it becomes a long list of request/response messages.
Not all the messages (my requests and AI answers) are important.
It could be great to be able to remove what is not necessary.
If you started a thread that’s just a quick tangent, I recommend editing your response before it branches so you get a continuous meaningful conversation. (I can draw a diagram if the explanation was too obtuse. UX is difficult to put into words)
