Thanks for the theme. Not sure if this is within the scope of support; but I have the Visual Portfolio plugin enabled and while using the pop-up gallery in a mobile device, the navigations clashes with the plugin. So instead of swiping left to go back to the previous picture, it brings up the menus. While viewing pictures horizontally, the top menu/search bar is not removable.
As the issue is arising due to the plugins used, can you ask in the respective plugin support forum for a better solution? Also, if the issue still persists, can you search for another plugin for the same in the WordPress plugin directory.
