Today, Google announced two, small improvements to their Gmail web interface for mobile Safari: scrolling speed and the toolbar availability. First, scrolling: Google explains that the new scrolling on gmail.com is now “snappier” and better reflects the speed of an inputted swipe gesture. The second feature improvement has the navigation toolbar staying onscreen when scrolling through mail — rather than appearing, via a short sliding animation, after a delay. “Being able to access your toolbars from any point on the page should make it easier to triage your email and move around the app,” writes Google. The new features are available in mobile Safari for iOS versions 4.0 or higher (English only, for the moment).
