Display the original question beneath the answer edit form
In the Auld Auld days of Stackoverflow, we had a separate Answer this Question page.
Now, there is an answer form at the bottom of the question page. It would help enormously if I did not have to scroll up and down to look at the question each time I want to verify another minute detail.
I suggest that the question's text should appear below the answer form as well. For long questions, it can be conveniently placed in a scrollable div.
