In the course of working with m0n0wall, the following aspects of the 
user interface caught my attention:

- I really like the way you van sort the list with DHCP leases. 
Something similar would be great for the aliases list and the list of 
overrides for the DNS forwarder!!

- The domain name that you give to m0n0wall is also given to the DHCP 
clients. I often find this a bit confusing. Perhaps a separate field for 
the DHCP client's domain on the DHCP page for each interface for which 
DHCP is enabled?

- Someone else also recently asked about this: it's not always clear 
what implicit, automatic firewall rules there are. A static display of 
these along with the "user specified" rules would be very neat.

There will be more, but these have been on my mind for some time now...
