Option to for distance measurements in miles

[Phrogz]

Settings section has a lot of units (with an odd alternation of which side metric and imperial are on...but I digress). Measuring distance shows km and Nm (I assume nautical miles), with no way to see the distance in miles.

Please have pity on a poor American who just can't think in km, and add a Setting for distance units, and include "miles".

Thanks for a lovely product!
