Module or section to post notes or basically a blog by day if desired. I realize there is a note section so maybe it could be setup with preferences for dates or such. Right now if that gets a lot of entries sorting or searching for some thing specific may become difficult.
I envision, for fields, Date,heading, people met, weather conditions, and a body for blog entry. Or perhaps a way to tie it to a blogspot address where it can pull that into the program but not necessarily store it.
