Often I'd like to open a file in a subdirectory. But poor me, I can't remember the name. So when typing
C-x C-f and then
TAB TAB for the completion list, the list of all files in this directory is listed, including the subdirectories, which are only marked by a
/ at the end.
Any idea how to highlight the subdirectories in this buffer
*Completions* or to sort the completion list
