I believe it doesn’t make much sense for the copy button to include the quotation marks and the comments the tool makes around the text. Users only want to copy the translated or improved text. After copy/pasting, we have to delete the rest and the kind offers to keep helping, which results in unnecessary extra work. Sometimes excessive if, for example, you are working on a long movie script. I suggest you that the tool copies just what needs to be copied, not the whole text showed.
We have that for code. When it generates code there is a copy button just for the code. I think this is a valid improvement that can be done on ChatGPT.
