Found a few little ones
Locations and exclusions can not be removed from policies.
The only option is to stop engine, then delete in registry.
Pointer domains get listed in the domain selection when editing email options from a user properties screen.
IP Black hole settings not saved if firewall options set to disable, and some other circumstatces I haven't quite pinned down yet.
Traffic monitor interfaces often read as NDIS 5.0 Driver. I'm sure they have a nicer name :-)
Things that would be nice
Join a VPN from the VPN properties screen. Can't currently to this
Cant black hole from the Syslog - that would be awesome.
History database filter needs 'Begins with', 'Ends with', and a NOT modifier
Thants all for now
