In our DEMO version, we used additional extensions such as AcyMailing (acyba.com), Kunena Forum (kunena.org) components, and as well as several JoomShaper and default Joomla! modules, here is a full list of them:

• SP LMS (component + modules)
• SP Simple Portfolio
• SP Page Builder (Pro)
• SP Flickr Gallery (module)
• Acymailing Starter package (component + module)
• Kunena Forum (component)
• Custom HTML (module)
• Breadcrumbs (module)
• Search (module)
• Menu (module)
• Articles - Lastest (module)
• Articles - Category (module)
• Tags - popular (module)

The additional extensions included in QuickStart are not required for the template to fully work. But they can be used to get the full functionality of your website, in the most advanced and recommended way and always upon choice. Most of them you can replace with others taken from JED. All extensions are 100% independent from each other. Using a Helix3 layout structure, the modules can be set one on the other like Lego bricks, making up a detached website within the hour. More JoomShaper extensions can be found on the  joomshaper.com/joomla-extensions page.
