The Color Coded Events Bar displays along the bottom of the calendar. Frequently I inadvertently disable showing events of a particular color from that bar while trying to swipe up from the bottom of the screen to access the Android Navigation bar. If I don't immediately notice it, I've frequently double booked a date in my calendar, and on occasion missed an appointment, because something I already had on a particular date was accidently disabled from displaying when trying to access the Android Navigation Bar.

Putting something in the Settings Menu which allows that Color Coded Menu Bar to display at the TOP of the screen would eliminate this frustrating situation.
