It would be great to have a feature (as exists on other platforms) that provides an internal (LAN side) virtual NAT, to allow one IP address to exist as virtual IPs on other vlans

eg:

Say i have a printer.  i can only set one IP on this printer directly, it does not support vlan tags.

With virtual NAT i could give it an IP in other networks, rather than having to setup up switch ACLs to allow other networks to access it - this saves both ACL rule count and would be much easier to manage.
