Gmail interface could soon look very different from the services that currently known. Google has invited a select group of users to test a brand new interface for Gmail. Test version of Gmail, which may never occur formally deviates from the design elements that have been present since the early days of this service. Sidebar is replaced by slide-in panel display. Keys, such as “compose”, are located in the bottom right corner. In addition, Travel, Purchases and Finance tabs are now joined by current social, Promotional, and Updates Forums by tabs. There is another new feature – reminders that should notify the user about future dates and answering some emails. Google is known for its testing services, and now we can not know whether the current test will be implemented in the Gmail service in the future.
