Will definitely test it, it's definitely in the early stages and more basic stuff oriented but after using the majority of the fancy and more feature complete tools available today like Caddy and Traefik, a GUI is more than welcome.
Actually now that you say it: why is no one just putting a simple gui for editing in traefik. GUI debugging in the dashboard an Jaeger is already great. And the yaml syntax is so simple that it should be easy to model a UI based on it. I only found a five year old project.
If you make a script that handles building the traefik config from various inputs, you could make a gui config for it with Configurator [1] which we built and open sourced to make it easy to config stuff!
