Maybe I'm having a premature senior moment, but I'm sure that when editing an answer there used to be a link to the existing answer - which I used to use to bring up the original question in a separate tab. It was fabulously useful, but it seems to have gone.
Am I delusional?
If not, what was the reason for removing said link, and is there any chance we could have it back please? (Or have a copy of the question in the edit page, probably collapsed to start with but expandable.)
