Description
In options DNS servers (System: General Setup) there is an option 'Use gateway'.
But in the dropping list there are names of interfaces, instead of gateways. And accordingly the functional does not work.

It uses the gateway specified on the selected interface, it's a way to associate DNS servers with a particular ISP. If you need to use something other than the primary gateway on the interface (which is rare), you can choose none and add a static route.

It seems to me, it should be added in the remark to an option.
If you need to use something other than the primary gateway on the interface (which is rare), you can choose none and add a static route.
If to use rules pf it will be possible to specify group gateways for failover.
For example so:
pass out $GWFailover proto { tcp udp } from any to ##DNS_IP## port 53 keep state

yes that's all possible. You can do that manually as well, with floating rules. It's definitely something we should consider in the future. It's not a bug though, it works as intended.

I just gave it a try with floating rules, but tcpdump shows that still the default GW interface is being used for DNS resolution.
Chris, is there anything to be taken care of specifically in order to get this to work?
