In the menu Settings/Localization there are 4 entries for units (length, altitude, speed, angle). Would it be possible to display the selected unit below each entry head line, i.e. replacing the small text line "Choose default display units", "Distance units for height", etc. by the currently chosen unit? Now I have to go into each one just to see what is selected. I have seen this solution in other apps.
