Maybe you noticed it already. VersionEye changed the CSS implementation and is responsive now. It was a switch from Boostrap 2 to Bootstrap 3.3.5. Now the layout is floating around depending on the viewport of the device and on mobile you will see the typical burger menu in the right upper corner.
Specially the search results and the product detail pages have been optimised for mobile.
And the user profile pages as well.
It was a lot of work migrating from Bootstrap 2 to Bootstrap 3.3.5, but it was worth it. The pages are looking much cleaner now and they are usable on mobile. If something looks odd please open a ticket here.
