Google play store New CARD STYLE layout
Google is rolling out new Card style layout in PlayStore. This enables user to swipe through installed apps. This is a server side switch so updating the App won't give you the new layout you'll have to wait until google does it for you.
The card style layout will make Play store more easy to Handel and fluid.
This video was posted by some user on G+ community. Many people have reported that they have got the new ui some hours before. X9techno team still hasn't got the new ui thanks to G+ user Rony for video.
