I've made a modification to the app that some users may find useful. Now, the "Units-of-Measure" and "Suppress Off-Course Reminder" settings can be OVERRIDDEN in a PROFILE. All new Profiles, or those you previous defined, will automatically defer to whatever the primary setting is for these two options (thus all your existing Profiles will work exactly as they did before this build). However, you can now edit a Profile so that it explicitly overrides one or both of these settings.
Build 31 should show up on Google Play shortly after this message is posted.
