The blue circle thing on the Chromebooks seems to serve no purpose. All it appears to do is just stay on the screen and remind you that the school can see what you are doing. If it watches our screen, doesn't GoGuardian already do that? And it blocks clicking things near it so I have to move it around a lot just to click on something. 

The district could have a good reason for implementing this feature, so if anyone has any information about why they added it, please contact me at sentinel4470@gmail.com

Here is the official company website for the circle: lightspeedsystems.com
