i have 5 profiles and everyday i have to switch on then many times, every time i have to swipe down the screen, press the icon from the current user then choose the profile i want on that moment to login.
i think graphene developers could add the SWITCH PROFILE OPTION on power button. so if power button pressed (two times or three times) it would show up a menu with all the profiles to choose.
QUICKLY "USER/PROFILE SWITCH"
