Would love to see a field that displays the number of a task within a list.
Adding another task, increments the number by 1.
Sub tasks are numbered after a period.
Task = 1
subtask = 1.1
When a task is reordered (e.g. drag and drop), so is the number and any other tasks and subtasks below it. A view may need to be created to maintain this and this action can only occur in this number/order view.
If the tasks that are numbered are sorted in a different way e.g. by Priorty then the numbering of task/subtask should should not change
