Option to show only clients with MAC addresses

Sometimes, clients won't respond to pings, but you'll still know they're on the network because their MAC addresses manifest. But Angry IP Scanner has no way to filter out all the unused IPs and keep only the present ones. It either displays all of the possible IPs on the network ("All scanned hosts") or only hosts that respond to pings ("Alive hosts"). There needs to be an in-between option to see the present hosts, not just the ones that respond to ping and not every address in the subnet.
