Subtasks work well, but in some situations I find that I want to order items in a sublist differently from how I order them in the parent list. RTM doesn't allow that. There are cases where I want to have repeats on subtasks AND tasks.

The best way to work around this is to make the subtasks into a separate list. But it would be great if I could link to this independent list from within it's "parent" task to allow increased functionality. Perhaps a new task field that on click takes you to the other list?
