A coordinate conversion utility would be nice...

Im in the reserves and am also actively involved in search and rescue work--a simple add-on "calculator" enabling you to convert between lat/lon and MGRS/UTM would be a nice feature. For example, you may be at Point X. You may need to direct someone to Point Y. Id like to be able to convert Point Ys coordinates from lat/lon into MGRS, and/or UTM. That said, this app does it what it says it does without any muss or fuss.
