Scott,
"The picture on the folder in your example; while it does the job, is really small and hard to see compared to what we had before, and therefore another step down."
That was a reproduction Scott, since Windows 11 won't do it and I don't have any screenshots from when Windows 10 was installed (that I can readily find.) In '10 the resulting icon were a large size, that you'd be used to, except it'd have your selected picture on it.
(Still haven't found a screen print! 2/2023) See page 3 of the thread and the post from azhotaz
Thank you, azhotaz for your clarification!
