Support for editing ERB Rails html.erb

Hi Guys!

I think it would be great to many devs to able to see live changes to their .html.erb templates without having to just start a html version and copying/editing into the html.erb pages.

Right now, we would have to go and design in Pinegrow, with attached css/framework/js and then still manually copy over all code to vews one at a time, is there any plans to support fully or maybe there is a better way to work like this when building Rails App templates?
