I'd like to modify the Rally Kanban board so that it only displays leaf stories, just like the regular backlog.
If I could simply change the query so that it only returns stories without children, I'd be done. But unfortunately, I don't see an obvious way to change the query in the config item to accomplish this, since you can't query on the "Children" attribute of user stories.
What's the easiest way to do this? Can I post-process afterwards and easily not have it display cards that have children?
