The latest update to Google Meet makes some settings "sticky" after you implement them. Now when you disable screen sharing and or chat messages for students in a meeting, that change will apply to future meetings that you host in Google Meet. I like this change because it's just one less thing that I have to think about at the start of a meeting. Of course, if you want to undo the sticky setting you can do that by just re-enabling screen sharing or chat in your next meeting.
This isn't a huge update, but it should prove to be convenient for many teachers. This update is rolling-out now and should be available to all teachers using G Suite for Education in January.
