I often find myself retrying prompts multiple times and wishing I could just pick bits and pieces from each response. Of course I can do that with copy/paste, but an integrated feature could make this a breeze.

My idea is to trigger a rewrite with the option to stash the response into a separate section without losing the original text. A nice variation would be to make a selection of the rewrite and stash only that, allowing you to build a scene with only the best pieces from each response :)
