Creating an efficient UI is paramount to a good user experience. If the design is cluttered or confusing, there will be less reasons for users to use an app or service. Google has made some changes and improvements to Chrome’s UI over the years, one of which is the introduction of the Duet interface on mobile.
This introduced a button at the bottom that when you pressed, would jump to the address box where users could perform a search. However the only “problem” was that based on the current iteration, it would highlight the existing URL which confused some users. Google has since “fixed” that in the latest Chrome Dev where when the button is pressed, it will take users to the address bar as per usual, but it will also clear it so that it is more intuitive to users that they need to type.
As you can see in the screenshot above, the version on the left is the old Chrome, and the version on the right is the new Chrome where the address bar is empty. There will be a microphone icon for voice search, and there will also be the URL of the website you’re currently on below it where you can tap to edit it or copy/share it.
