Is it possible to have a preference to show imperial dimensions in all fractions?
Conventionally, imperial dimensions are not shown with a decimal. For example 5' 5.5" would be conventionally shown as 5' - 5 1/2".
Perhaps with the preference, the rounding of the fraction can be set too. For example, have the dimension display to the nearest 1/64, 1/32, or 1/16, or 1/8, 1/4, 1/2, etc.
