Some sort of “factory reset” functionality would be nice if you ■■■■■ the stuff up completely and want to start from scratch. 
I also vote for this improvement. Could u just provide a defaults button in settings which will restore it to the factory defaults.
Then we will feel confident to mess with them and tune them to our own likes.
Like this one too!
Saves people from removing all policies if they want too, etc without uninstalling & re installing.
