Hi everyone, I’ve tried to customize our discourse for about a month.

Then I’d like to ask why mixes widget and handlebars together?  
I think that makes code more complicated and hard to maintain.

For an example, I want to move `Create Topic` button to header, then I just realized the button is created in hbs but header is in widget.

I really want to know the reason why you want to combine different things together.  
I know for performance issue widget is a good tool, but don’t you think that is harder to trace and revise?

And there is another question: Does anyone know how to trigger event in widget from ember controller?  
I’ve been stuck on the confusing architecture for a while..
