When the Kindle Fire first came out you could delete or favorite items from the Carousel on the home screen. A new feature of the 6.2.1 update, is it lets you remove items from the Carousel and Favorites.
The Carousel is at the top of your Kindle Fire home screen. There you can scroll through recently used items with a cover flow like experience.
To remove an item, tap and hold the icon until the dialog appears. Then tap Remove from Carousel.
Favorites are the items below the Carousel. To remove an item, tap and hold an icon and select Remove from Favorites.
This tip helps keep your Kindle Fire more organized and lets you hide embarrassing books you’re reading.
