I would like to have a feature to implement colourful tail log on the pi, as this would make debugging a lot easier. No need to ssh.
Red for blocked, as it already is
Yellow for clients' query, including A, AAAA, PTR, etc
Green for reply to clients, ie replying an IP
If DNSSEC is enabled, use magenta for BOGUS
White for DHCP
Orange for warnings, like NXDOMAIN or things that the user needs to be aware of
Any remainings should be coloured as purple or sth like that
Blue is not used because the windows powershell is blue. If blue is used it would be hard to see for powershell users
I think adding colours to the web interface would be as simple as just adding colours to the text, depending on the content. Like colouring lines with "blocked" as red, "query[type]" as yellow and "reply" or "forwarded" as green. This would make debugging a hack lot easier.
I believe colourblindness should be dealed with system level accessablity options. Anyway, they all have text to convay meanings, and not colours only. And I am just suggesting a colour palette, to give a example.
At least, change the grey to something else, it is really hard to see.
Edit: I don't think thay are that hard to distinguish...
