When editing and creating new features the line segment, angle, and area measurements (polygons) are shown in the bottom left of the screen. This is useful information. However, the measurements and units shown are in the Map Units for the Data Frame. If the Map Units are meters, then you will see the linear distance and area in meters. It would be a great help if there was an option to change the displayed measurement units in a different unit (for example feet) independant of the data frame map units.
