MT Quartz lets you create your custom sub-themes (theme variants). You can create season-specific designs to change the look of your store for fashion, computer, sport, estate, beauty, kids etc.
That’s very useful and very easy because MT Quartz is independent from Magento’s “default” theme it’s a separate design package.
