Just got my new homescreen how I like it with Zooper Pro and Nova Prime on my Moto X.
-Tapping on the clock opens the clock app so I can set an alarm. When there is no alarm set, it disappears from above the clock.
-The picture opens my wife's contact to call or text.
-The search icon opens voice search.
-The "..." in front of the battery level appears so I know it's charging. When it's off the charger, it goes away.
-And the calendar entries open the calendar app.
The icons are Minimal UI edited to be round with the Icon Changer app.
