Is it possible to have items as a parent to other items? I have a whole load of projects that have little sub-tasks that need doing, it'd be nice to be able to have a task open for the project, and 'child' tasks for that, or tasks that are linked to the original. I'd rather not give a whole tab/category to each project, since they're not quite large enough, and so frequent. Ideas? Could it be a feature request if it doesn't exist already?
