Recently, almost all Google products have undergone changes in design and usability, most of the new integrated social network created by the company, Google +. However, as in many products, especially your search, the flagship company of the change in Google Calendar is only aesthetic.
Some colors have been enhanced, modified and faster buttons are the highlights of what is the biggest change of style from Google shortly. Changes to streamline the work were also made, such as creating a button called Create, followed by a Quick Add to add more content quickly and easily. Other buttons such as Print (print) and Refresh (reload also been implemented at the upper right corner.
In the left corner, where you can view your calendars and others, now the menu is tight, and you will see its markings only when you click, making the menu more cohesive. The buttons to save and return to the calendar came out of the bottom of the page and are now at the top. But if you do not like this design or not used, no problem.
Just click into gear, there in the top right corner, and click "use the classic look." Soon, more Google products will be aligned with the new design of Google +.
