If he's trying to disable it to prevent people from being able to change to any room they want, this is a bad suggestion. Someone could just send the packets to teleport them to other rooms based on their ID and get around the front-end hiding it. They could also just set it to show in dev tools. The proper solution would be the emulator tells the front-end not to show it, and the emulator is updated to prevent the navigator packets from doing anything.
