Power Store 4 is vastly different from Power Store 3 in the way that pages are put together.
Power Store 4 uses the theming and plugin concept of Framework Builder:
framework-builder/
I dont think a screen shot of a power store template will be of much help.
In power store 4, the template is just the page structure of editable regions.
Framework Builder Themes are applied to the Template to give the page it's design.
The themes can be edited using the online Editor tool in the Power Store Admin section.
