LivePreview: WordPress Theme Demo Bar
Those of you who have bought WordPress themes from template sites in the past have probably seen their theme demo bar. This is a simple tool that allows customers to switch between different products fast. LivePreview can add such functionality to your own site. It lets you switch between themes, HTML templates, and other digital products with a simple click.
LivePreview is a responsive tool. You can customize the style to make it match your own design. Your visitors will be able to switch between themes, view it in different sizes, or simply close the iframe to get it out of their way.
