Improvements to the interface for Gmail and Google Calendar are now available to preview via an Opt-In setting. These changes will be rolled out in full later this year, but you can test the sleeker look immediately.
To enable the new look in Gmail, click on the gears icon and choose ‘Mail settings.’ On the Settings page click on the ‘Themes’ tab and select the ‘Preview’ or ‘Preview (Dense)’ theme.
To enable the new look in Google Calendar, click on the gears icon and then choose ‘Try the new look.’
