I would love to see DNS based Health checks

something like

type: dns
    url: "udp://127.0.0.1:53"
    queryname: "host.example.org"
    querytype: "A"    
    conditions:
      - "[STATUS] == NOERROR"
      - "[DNS].response == 1.2.3.4" 

Style disabled forward (or back) arrow so that it is faded from its enabled (white) style instead of faded dark gray.

This is a minor adjustment.. it would be a major project to set up my development environment. So, here is the minor change I would do if I could do it.
