The Google Classroom Team always listens to feedback from their users. Being on the team, I know first hand the Googlers value your feedback, and they prioritize it accordingly. That is why I always stress to users in the forum, to always leave feedback by clicking on the ? at the bottom of the screen. The animation below shows how to send feedback to the team. You can also click on this link.
An important update in Google Classroom was the enhancement of the email notifications. In the past, you only had the option to enable or disable them, and this was a global setting. This would flood your inbox with emails.
Now, you can specify what type of email notifications you would like to receive from Google classroom. It is still a global setting, but now you have the option to enable/disable notifications so that your inbox does not get overloaded with Google Classroom notifications. The image below displays all of the options you can enable/disable for your email notifications.
Additionally, you can change your profile picture in this area too.
Continue to leave your feedback and you may see your suggestion implemented in Google Classroom.
