 The Layout Inspector in Flipper is useful for a ton of different debugging scenarios. First of all, you can inspect what views the hierarchy is made up of as well as what properties each view has. This is incredibly useful when debugging issues with your product.
 
 The Layout tab supports [Litho](https://fblitho.com) and [ComponentKit](https://componentkit.org) components as well. We integrate with these frameworks to present components in the hierarchy just as if they were native views. We show you all the layout properties, props, and state of the components. The layout inspector is further extensible to support other UI frameworks.

 Leaks detected by LeakCanary will appear automatically in Flipper. Each leak will display a hierarchy of objects, beginning from the garbage collector root and ending at the leaked class.

 The Sandbox plugin is useful for developers that had to test changes of their apps by pointing them to some Sandbox environment. Through this plugin and a few lines of code in the client,
 the app can get a callback and get the value that the user has input through Flipper. At this point, the developer can plugin its logic to save this setting in its app.
