We've added Design Preview controls on all our demo sites, which let you see the same website in different design skins. Some of our skins have several theme options, and you can toggle between these as well. This is a great way to imagine how your site might look in different designs.

We've done a ton of updates to old and new design skins, and released them as 2.0 versions that are now the defaults. But if you are using a version of the free designs skins from before 1 week ago, or you have an old custom design that is perhaps getting out of date, is not HTML5 compliant for mobile devices, etc., we really recommend that you switch the design on your site to one of our updated free design skins. They have been given a lot of attention to detail at every level, e.g. the modules are styled to look good in every context, there are modules were they weren't availalbe before, the code is overhauled and more HTML5 compliant, etc.
