This is not a question but a certain critic of nopcommerce design and themes. Since the market is sliding quickly to the mobile devices, responsive design is essential.
The default design of nopcommerce seems responsive but specially the header section design is outdated. It should include a collapseble navbar
menu instead of the current design for mobile. I will manually change the css and collapse my site header
Unfortunately only a couple themes support such design. If nopcommerce would like to compete in the market, it should better update the front end as soon as possible.
