RMRTask (Nokia) - Extended ToDo Manager   
by RMR Software   

The program is designed as an alternative method to the To-Dos in Calendar for recording and managing your tasks that have to be accomplished, whether at work, at home, for hobbies or for personal goals. It uses the principles of good time management, namely breaking down large projects into tasks of manageable size, categorising and setting priorities for tasks, sorting and ordering them, and being able to see progress, results and accomplishments.
