Feature Request: Support for Lists with Sub-Tasks (Sub-Lists) #108
Description
It would be great to have the ability to create a list and add sub-lists as sub-tasks. As soon as a list contains sub-lists or tasks, it should automatically change to the same color as if "R" was pressed/clicked. Additionally, the sub-lists/tasks should be bound to the main list so that dragging the main list also moves all associated sub-lists/tasks.
