Rob - excellent work!
So far so good, no crashes. Interface looks clean (I don't care for the brush metal, but that's minor).
Here are some minor notes:
You said:"New Feature: replaced Garmin calorie calculation with a different algorithm that should produce more accurate results". However, calories are not been computed at all (I got a Garmin 205)!
You said: "New Feature: updated "User" preferences to include "Birth Date", "Gender", "Height", and "V02Max". Also added calculation for Body Mass Index (BMI), and user picture." How do you add user picture????? I tried dragging, but it doesn't copy...
Keep the good work!
