The Starred Frameworks widget gives you quick access to the frameworks that you use most. Starring a framework adds a direct link to it on the Products / Services page.
To star a framework, just click on the hollow star icon besides the name on the framework page. Once the icon is highlighted (as below), you have starred the framework.
To unstar a framework, just click again on the star icon on the framework page and it will remove the framework from your list.
