I came across an answer that would have worked for my question, except the new layout in 2.8 has moved that item and so the answer was useless. I could ask a new question - but then, people who google the question like I did are probably going to be directed to the old question, and it won't help them. Also I've always found it difficult to effectively search for what I need on the Blender SE, and so I would hate to mess up this question's relatively good searchability.
So I daydreamed about some happy way to flag questions like this for updating. I know that only a small minority of users would so flag, but maybe that would still look after a big chunk of the issue. Do you think there is any good way to do this?
This is the question that led to this: Viewing normals in Blender?
