Hi James, thanks for feedback! It is very helpful, since you've shown us that we need to demonstrate the relation b/w tasks, goals, milestones and backlog more clearly. The backlog holds tasks and goals which haven't been assigned to a milestone. Each milestone has its own tasks and goals (but you can move them to another milestone or the backlog if you need). In general, all the interesting stuff happens in milestones, while the backlog holds tasks and goals whose time has not come yet.
