It would be nice to have an ability to define component's CSS the same way as HTML template.

MyComponent.html -> template (already implemented).
MyComponent.css -> style for component (scoped style support is nice to have as well)

That would be a nice feature indeed. Not sure if we will have time to implement it soon though. If someone wants to try they are welcome to it. It would be nice to use GWT generators to a minimum for this (see how the HTML template GWT generator is done), or even use an annotation processor directly.
