Presentation Mode is useful, but it's also easily forgotten once enabled. This could even have security implications, if one trusts their workstation to lock after a certain amount of time. Therefore I propose that the power-manager icon gain another smaller icon or something as an indicator that presentation mode is currently active. Thanks!
