So you want to know how to customize your (School) chromebook huh? Well then i got just the thing for you. You know there is something called Dev tools. Dev tools can be used to find hidden settings customize UI and even get rid of the certificate on your chromebook (which is illegal) thus letting you do anything to your chromebook enabling any settings you want downloading any apps you want letting you get rid of that stupid relay app that blocks anything you go top allowing you to play flash games and go to certain websites and even run .exe files. You can find these developer web pages at chrome://chrome-urls/ and you can find the device mods at chrome://flags
