View → Categories

To add details about the progress of you task, select:
Options → Status Details

A dialogue box will display where you can enter details like the current state of the task, the percentage completed, priority, etc; click "OK" once completed:

When you have entered all the data you require, click on the save icon in the top left of the dialogue:
