The latest version of Google Voice includes 2 new Widgets to facilitate the use of the program. One of the more annoying features of Google Voice is trying to decide if you want to use Google Voice to make all your calls, only international calls, none of your calls, or to prompt you on every call. If you, like me, use your Google Voice number for work and your primary number for person calls (or vice versa) you probably have to set the app to prompt you on every call. One of the new Google Voice widgets makes it easy to toggle between these settings.
The other widget displays the most recent message in your inbox. There are right and left arrows that make it easy to cycle through all the messages on your inbox. Pressing on the message opens the app to that message.
