Tech Professional ---> Little dumbness

Such a humorous thing! My Professional IT friends best in their fields at NIT Jalandhar got so amazed to see this feature and they hadn't done it till day that they can change their gmail account just by swiping down the avatar symbol. They were so amazed that they used to manually change it and didn't even knew it till now. Are your friends or you also too techy and a little dumb to get amazed by this feature
