No way to create subitems i.e. when the subitems are completed, the parent item is completed? The main thing I need out of a task manager is for it to allow me to decompose and refine tasks, and to keep track of that stuff as it gets complicated. If the data format doesn't even allow for subtasks, that seems impossible without abusing tags.
edit: I now see that it's the top issue on your bugtracker.
