I just installed version 2.20 on my local system using the Web Platform Installer as I could not figure out how to manually install the new version from scratch. I had installed 1.8 a while ago and have come back to try Nop again and am trying to use 2.20. In the past there were master pages and modules that I could then edit to change the default look to one that I created myself and could add custom jquery to the headers and add custom pages if needed. In this new version, I do not see how I can create a custom theme or add to the site or how I can add custom scripts or how to create a custom page from scratch. I do not see anything having to do with modules, master pages or anyway to edit outside of the admin section of the site. Please help as I would like to use my design and add jquery to create a drop down navigation and other functionality as well. I have yet to find where the files are stored that I can edit as I did in 1.8...

Thanks
