Response Trees

The idea would be similar to what OpenAI has now: Allowing you to go through multiple already generated messages on the same response with arrow buttons.
It’s becomes increasingly irritating to accidentally press Regenerate instead of Fork or Voice, deleting the message outright. While Forking conversations helps, there’s the chance that not all of the chat is copied over, or the messages become disorganized for some reason.
Being able to look through the responses you’ve re/generated for a single message would be a massive step up in keeping the side-panel from overflowing with forks, or going back to one you believe to be better in a hurry.
