This plugin offers you the ability to add custom page template files to your WordPress installation without having to manage 
theme folders or use a ftp client. Simply upload the custom template file you have been working on and it will be registered 
with WordPress as a template option for your pages. This plugin is straight to the point and has a clean user interface using 
W3.CSS.
