This topic and its associated topics explain how to customize the order of information displayed in the To-Do tabs.
Each of the To-Do tables is sorted by default according to the update or due date, as applicable. The parameter according to which table information is sorted is indicated by an arrow above the parameter name. A downward pointing arrow 
means the cells are sorted in ascending order, and an upward pointing arrow 
means the cells are sorted in descending order.
In the To-Do tables, you can customize the sort order.
