The Google Tips is a presentation of most Google’s products, displayed in cards, showing important features of each product. They are also divided in categories like On the go, At home and At the office, and at the end you can enter your own card.
At the bottom left corner there is a button called Feedback, where you can enter your own suggestion to Google. It’s interesting that even with billions of customers around the world Google still has time to read your suggestions. So go ahead and send something.
