Custom Customization

Hello, great plugin and an awesome job done. However I want to know if it is possible to edit the theme’s template. I’m developing using a custom theme from underscores.me having installed dummy data the home page, listing page etc have all been installed and pre-styled in way. How do I use my custom template and if possible re arrange all the components from maps to listing to forms etc the way I want.

Thanks for your prompt response.
