Thomas,
If your "main project" doesn't have any tasks (but only subprojects) couldn't you put all the subprojects in a folder and consider the folder the "main project"? That might work within the OF structure as it currently is. [Edit: GeekLady brings up a good point about the top object not being a folder, since the subobjects need to be sequential. Good point! Which means my following statement still holds.]

However I agree with you that the current project/task/subtask design is poor.
