I second this... Using GeocacheNavigator for paperless geocaching loses a bit when you have to carry a notebook to "jot down notes". Yes, I can put my field notes into another note recording application, but one would think that with all the whiz-bang features available in this application, one would be able to actually record field notes when one presses the button that records the field note. Having a note that says "Logged from my mobile phone" isn't a useful reminder.
While some may be in a hurry to move from one cache to the next, others may want to jot down a couple quick reminder notes, while others may want to take the time to write up a complete synopsis. Flexibility is the key to creating excellent software. Give everyone the options that they want, and all are happy.
