Hey Marc,
I tried copilot using the current beta3 version and it works quite well. I tried a few things you showed in the town hall meeting and can confirm they worked as expected 
In addition to that I tried a few more prompts:
- “Change the theme to dark”
- “Change the icon of the menu item to be a light bulb”
Here are a few use cases (or prompts) I would like to use Copilot for:
- Add a dependency for spring-boot-starter-data-jpa to my project.
- Add a POJO called Foo with the following fields in the package com.example.application.entities to my project: id, name, email.
- Add a Spring Data JPA repository for my entity Foo to my project.
- Add a BrowserCallable for my entity Foo to my project.
- Add a new view called FooView to my project.
- Insert a AutoCrud component into my FooView using FooModel and FooService.
It would be nice, to be able to use Copilot for those kind of things. I can image, that it is quite difficult to extend Copilot to support this kind of full stack tasks.
One last thing I would like to highlight: Thank you, for making me a Vaadin employee
