Custom Product Tab Types is a new feature in the Smart Tabs plugin that allows you to add different types of tabs, such as Content, Image, Video, FAQs, Download, Map, Contact Form, and Products, to all products, specific products, product categories, or brands. 

After adding product tabs, you can also override the tab content for individual products directly from the product edit page by entering different content there. 

Click on the Add New Tab button to create a new tab. By default, there are three tabs available: Description, Review, and Additional Information. You can choose to disable these default tabs from appearing on the single product page if needed.
