According to the latest information, it seems that the capability currently launched is very limited, this new online version of the Google Play Store design has largely borrowed from the design of the mobile application.
Moreover, the redesigned Play Store Web comes with an application preview, the ability to install apps remotely, and support for movies and books as well as apps and games. It also added a new application tap that displays top charts, popular apps, and app filters.
However, we can easily access this new redesign just yet, as it appears to be released on a server-side switch but some regional variations of the Play Store web client have been successful in enabling the new design. At the moment, it is not confirmed whether Google will release this new design widely.
