Google's Vic Gundotra announced some improvements to Google Hangouts today, including support for SMS, animated GIFs and location sharing. While support for animated GIFs is sure to send the BuzzFeed faithful into a tizzy, it's SMS integration that's the truly major news. The feature was rumored to be coming in Android 4.4, which we already know will include support for changing the default SMS handler. Now you'll no longer have to use the separate SMS application included on your phone, text messages will simply be delivered to Hangouts the same way instant messages are. Obviously this is just one more step in Google's modularization of Android, slowly breaking apart the "stock" OS into easily installable bits. Unfortunately, there's still no word on integrating Google Voice with the burgeoning messaging platform. Location sharing is also being baked in, with a simple button (next to the button used to insert photos) that locates you on Google maps and lets you dump it into your open chat.
