The DashClock Widget is one of the most useful, customizable and along with its various functions, there have also been a lot of extensions from various developers, which makes it even more functional and interesting.
Also, Roman Nurik, developer for this useful application, has taken to Google + to show what the Daydream support can actually do. The DashClock Widget is a lock screen widget that many people found quite useful since it combines all the other important widgets that you need to give your device extra functionalities.
Among its improvements are better translation, date localization is more accurate, improved weather due to Wunderground API, improved API and Daydream.
Daydream allows your phone to display whatever you choose when it is on idle mode such as information that you might find useful, while you are not using your phone such as battery life remaining, photos, weather, etc. More and more developers are using daydream to extend a device's functionality, even when you are not actually using it.
