I dont know is this is a right place to request a new feature.
This theme is really gr8, simple and clean
I think the theme will be more good, if there is a theme options panel and a responsive default layout.
and once again congrats for such great hard work
i'm agree, but the idea is that you use this just as a base and then you implement your markup
Well, it doesn't have a layout, so it's arguably responsive. :)
This would be the latest version of _s theme options. We strongly recommend using the Customizer though.
Let's close as maybelater.
