Created attachment 454875 [details] Right now this is default page with expanded toolbar Currently, my progressive application is loaded in browser with expanded search toolbar on bottom. It is take a lots of application space on mobile device. Application is using Ionic Framework (which is has fixed body with hidden overflow) - unable to hide toolbar with scroll. There are no errors with push "aA" and select Hide Toolbar. Please add some <meta> tag to make "Hide Toolbar" option by default. It is should resolve many issues on JavaScript frameworks and progressive applications.
