Tabs are fully configurable in SD Release. These tabs will show up at your frontend on the extension detail page. Using tabs you can completely tailor your frontend as you wish. You can use tabs to link to, for example, documentation or simply show the changelog of the extension.
To start without much hassle, simply create 5 tab templates of the following types; changelog, description, reviews, screenshots and documentation. Then create 5 tabs using these templates. Group them and you've got a fully-featured frontend with all information your customers need.
You can create tab templates by creating a new file in the
/components/com_sdrelease/tabs directory. This file will then show up at the tab templates list, meaning you can select it for use. You are free to do whatever you want in these template files giving you full control over what to show.
