Details:

It would be nice if you could use -I substitution option with -n count option
together in the same command. 

E.g. 
$> var=/tmp && echo "one two three four" | xargs -n1 touch "${var}/{}"

$> var=/tmp/test && mkdir -p "${var}" && echo "one two three four" | xargs -n1
| xargs -I{} cp -v "/tmp/{}" "${var}"
‘/tmp/one’ -> ‘/tmp/test/one’
‘/tmp/two’ -> ‘/tmp/test/two’
‘/tmp/three’ -> ‘/tmp/test/three’
‘/tmp/four’ -> ‘/tmp/test/four’

Yet it would be nice if instead, we could: 
$> var=/tmp/test && mkdir -p "${var}" && echo "one two three four" |xargs -n1
-I{} cp -v "/tmp/{}" "${var}"
cp: cannot stat ‘/tmp/one two three four’: No such file or directory

Unfortunately we can't combine -n and -I substitution at the moment and I'm
not sure why not. It could be useful.
