Considering add comments to webui App.vue file


I’m new to Vue.js and also to concept of routing. It took me some time to realize that strings

are responsible for main contents display. Is it worth adding some comments like

     // This part is responsible for page's main contents
     // see ./route.js for details


Maybe it’ll be useful for somebody…

I can make a PR.

Sounds good to me, feel free to make a PR!
