Sorting requires flexibility. Most task management systems provide standard sorting but in many cases, sorting on set variables in the data is not enough.

ToDoMatrix allows a person to quickly and easily drag and drop tasks and folders into a desired order. This adds human intuition to your lists and makes a remarkable impact on the usability of the system. 

ToDoMatrix is flexible enough to allow the tasks with a folder or view to be temporarily re-sorted by a variable like modified-date, but later returned to human drag drop sort (we call this 'natural sort') without losing the order.
