Yahoo has overhauled its mail app for Android, adding a bunch of new features, including news, search, weather, videos and Flickr images. Yahoo said in a blog post that it hopes to spare mobile users “the hassle of switching between apps” and, ostensibly, to get people to spend more time in Yahooland. The app is now divided into three main sections, navigable by clicking icons at the top of the screen. The Mail section looks the same as the old mail app. An All Stories section contains personalized news feeds. And finally, a Today screen displays local weather, sports scores, news headlines, popular videos, and Flickr photos.
