Ext JS, ExtAngular and ExtReact components have a UI mixins configuration for generating multiple visual renditions of a component. Themer makes it easy to create and style UIs for a large number of components including Grid, List, Tabpanel, Title bar, and Form components. With Themer, you get access to all Sass variables to customize and create a distinct look for your application components.

With Themer, you can inspect component styles visually rather than going through hundreds of Sass variables. Themer provides a unique inspect mode that freezes the state of components and locks the styles, so you can easily apply different styles to various states of components such as hover, pressed, selected. Using Inspect mode, you get access to your application component tree, which provides a powerful way to navigate, select, and style components in your app.
