There is no indication in the Notes List if a note has attachment(s) when the option "Preview Text Lines - Minimum" is set to 0 (i.e. a compact list), Only when "Minimum" is 1 or more, do attachment(s) become visible.
It would be nice to see something like the attachment symbol on a note's Title Bar, similiar to the Link symbol left of a title.
As an added bonus, hovering over the symbol could show a list of attachment(s) with the ability select and open one.
