One thing sadly lacking is being able to read the journal entry as a single text file, with dated entries. Instead, you have to click through, day by day—that’s unacceptably lame.
OTOH, the chart functions are terrific, and charts can be exported as .PNG files.
The calendar view is very nice, and the weekly averages are invaluable. The ability to select with nutrients/micronutrients are included is extremely useful. However, it would be good if this view could be scrolled instead of jumping from month to month—e.g., you cannot look at a 4-week period that overlaps two months: you have to shift back and forth between the individual months.
On the whole, I have found the program to be extremely useful. I just hope that fix the minor flaws.
