Hey Mike,

If you just want a list of all the subtasks in a List, you can use something like:
list:YourList AND isSubtask:true

If you want a list of all the tasks and subtasks in a List, you can use:
list:YourList AND (isSubtask:true OR isSubtask:false)

If you want the list of both tasks and subtasks with some fancy indentation to show you which subtasks "belong" to which parent tasks... I'm not sure how to do that / if it's possible. :)

@mikecrum246 - Not sure it can be done.

impossible

I want this too!!
To be able to print 'all tasks' and have any subtasks printed as indents under the main task.
Pleeeeeeease?

This is an many years old entry. Not customer friendly.
Bad Subtask handling. I need a printed list over all structure levels, because I need task-lists for multi-project management. Only one structure level is not enough for me.
I am pro - but now I will look for another solution like ToDoist or microsoft todo. I am very disappointed about RTM. This is really not innovative.

It looks like there is no further development.

BOO! :(

Still checking out the features of RTM and this is going to be a show stopper for me too. I need to see all parent tasks & subtasks in a visual, ideally indented but definitely inclusive view.

This is disappointing as it is a really critical feauture in my view, and due to not having it makes the whole notion of subtasks useless in this service.
