Hello,
Thanks for the pull request, I will add it in my fork ;)

For information, this is enough to put remote client on first place without reversing the all array (which is configured in a specific order by user) :

array_unshift($hosts, array_pop($hosts)); instead of $hosts = array_reverse($hosts, true);
