How is the Importance field calculated?
The app uses Toodledo's formula. Here are the details:
Importance = 2+P+S+D
P=priority
S=is it starred (0 or 1)
D=0 if due-date is non-existent or further than 14 days out, 1 if due-date is between 7 and 14 days out, 2 if due-date is between 2 and 7 days out, 3 if due-date is tomorrow, 5 if due-date is today, and 6 if overdue
