In this picture you can see it uses a different color (lightgray) for the hidden files,
which is, in my opinion, a very clever idea, since the current way Nautilus displays
hidden files (like all other files) makes it very difficult to deal with them. Having
a color distinction would make me re-enable the ‘Show hidden files’ option.
