I think a simple web UI would make VyOS a lot easier for people coming from pFsense and it’s clicky clicky brethren to transition to.
I’m interested in helping put one together. If you’d like to help or just weigh in in on what the underlying webstack should be, design choices, or the priority of features please drop a line here or over on the slack #vyos-simple-ui channel.
The early JWeb implementations had this and it was valuable for on-boarding inexperienced engineers.
Having a visual representation of command/function hierachy (regardless of it being available to them in the CLI) really helped them solidify their understanding of the OS.
