It appears to work correctly, although I've yet to test it on large conversations. I love the header telling all of the information, love that it saves the file under the real chat name. BUT if you could add either word count, line count or message count that would be a good thing.

What this does for me as a long form fiction writer using the chatgpt as a platform for grammar and keeping me on track is allow me to download whatever chats I happen to riff in that day, bypassing Open AI's absolute refusal (or at least dragging it's feet) in getting those of us that are writing books something that allows us to download only one chat at a time.

Hopefully this is something that the creator will add later and continue to improve this add on, but for now, thank you!
