Google is refining its mobile app with updates that include a redesign of the built-in browser. Three new bottom bar layouts have been identified: one with icons for adding favorites and sharing content, another with a central "insights" icon for additional webpage information, and a third that rearranges these icons. A "double-decker" design featuring a search bar is also being explored. Additionally, the app's home page is being revamped with an icon-based carousel UI, replacing text-based input options. These updates aim to enhance user experience and streamline interactions with web content.
