Cleaning a working place and a working table is a good starting point to be organized. Organizing tasks is a good starting point to have time.
DevPlanner provides categories those different levels can be treated as a project, an iteration or a complex task. In some circumstances existent hierarchy should be reorganized to be simpler to understand and manage.
DevPlanner allows reorganizing tasks hierarchy. Category can be moved to another one, except self-descendants. Task can be moved to separate category or more dipper branch. Then category moved, all of its content moved accordingly, including subcategories and child tasks.
Moving categories and tasks is easy with drag-and-drop feature. To perform single category or a task moving, point mouse over interested item, press the left button and hold it while dragging to destination category.
