It seems surprisingly complicated. Why is there a “start” and “stop” button? Why does it take so long for it to generate a random string? Why is there a “console” that just seems to show the page template?
You right! Console and stop button are not necessary. The UI is generated with a UI creation tool that match program arguments with UI widgets (see: https://ibb.co/phQQFxr). In this case there is an option missing to don't show the stop button and the console (These are shown due that you can create interactive programs with browxy)
