Perhaps because I am used to the old style of Mathematica Documentation, the large thumbnails in the "Details and Options" section in version-11.1 Documentation look cumbersome and redundant to me. So I tried to remove them. But I did not find the code in the "Reference.nb" stylesheet that relates to these items.
So how can these thumbnails be removed? Thank you.
Actually I would like to completely restore the version-10 Documentation style, which I think is aesthetically better than the one in 11.1, but trying to do it by replacing version-11.1 stylesheet files with the old ones proved to be wrong.


On["Packing"]. (Visually, I do not mind the 'thumbnail'. It is only the broken implementation that bothers me.) – Szabolcs May 09 '17 at 10:21
