"Another minor but useful enhancement is FavLoc, which allows
you to designate multiple folders as download locations. These
folders are designated by name and path for easy identification,
and you can set where in the browser the list of them appears. The
concept is simple, but, if, like many chronic downloaders, you tend
to dump all your downloads in a default location and never get
around to organizing them, you could find this extension
indispensable for its help in getting you organized."
