@Anil: Sure, we will work on next version of this layout.
If we will get something for responsive design then it could be better.
Layout Templates allow you to choose how portlets will be arranged on a page. They are simple table or CSS-based containers into which portlets can be dropped and sit within the body of the page. Liferay Portal comes with several built-in layout templates, 80-20 Layout is something which is not available out of box in liferay portal. This layout will provide 80-20 column structure for portlet arrangement in a portal page.
This layout will appear in your Page Layouts once installed.
