It'll be great to have the ability to specify address lists from /ip firewall in /ip route - this would come in handy for all kinds of dedicated routing on addresses which are also handled in firewall.
This would also skip the mangle step to mark routing for those addresses.

Additionally, I'm sure that creating port- and protocol groups would definitely make firewall configuration easier...
Like getting tcp/80, tcp/443, tcp/22 in a group named "web server" and tcp/22, tcp/1723, gre/-, udp/500, udp/4500, ipsec-esp/--, ipsec-ah into a list named "VPN"...
Would this make sense even outside my brain?

Thanks,
