In-app browsers are usually not the best way to consume content in an app. In fact, Android developers have been using the Chrome custom tabs features to fine-tune the experience. Now Google is rolling out new features — such as partial custom tabs and auto-filling passwords — to make in-app browsing on its mobile operating system smoother.
The partial custom tabs feature gives developers more control around the initial launch height of a tab. For instance, they can have the tab open on half a screen when a user clicks on an article link. This allows users to interact with the app and in-app browsers simultaneously. Google says that partial custom tabs are supported by select in-app browsers including Chrome.
