Often when I edit one of my answers, it's because I want to better address the original question. The only problem is that I can't see the original question while I'm editing my answer!
I'd love to see the original question text beneath the "answer edit" form. This way I could scroll down slightly to read it if I wanted to, or just ignore it if not.
Current workaround is to click the 'return to answer' link and hope that you remember to launch it in a new tab/window, then tab back and forth.
