Google+ has now added a new feature called “Collections” to its social network. Collections is a “Pinterest” like feature which allows you to collect your favourite pictures, videos and posts around a specific topic of your choice. Your colections just like Pinterest can either be made public or you just keep them private
Google announced this in a post on its social network platform. To access this feature, you would need to update your Goolge+ Android app from the play store here. One you are through with this update, look out for the Collections tab in the drop-down menu below you Communities and Circles.
