Another DHCP feature I request is when a static lease is added, a static ARP entry for this IP Address should also be created.
I believe it has been there as long as I know RouterOS. (ARP is deleted when lease is terminated) see http://forum.mikrotik.com/t/cannot-access-access-points-gui-when-arp-reply-only-is-set-in-hotspot/143456/3 )
Beware the new developments in IOS, Android, Windows … of using random private MAC addresses per network/ per day / … by default.
