First off, this package is AMAZING and is letting me get rid of lots of handrolled/copypasted org-agenda cruft, so thanks. I'm like 90% of the way to replacing half of my emacs config file with a 10-line statement.

Second, I'm either doing something wrong or :children todo isn't working consistently.

Given this TODO item with children (but no TODO tagged children):

and this o-s-a group config:

    (setq org-super-agenda-groups
     '((:name "Active Projects"
              :and (:todo "TODO" :children todo))
       (:name "Stuck Projects"
              :and (:todo ("WAITING" "HOLD") :children todo))
       (:name "Pending Refile"
              :tag "REFILE")
       (:name "On Hold"
              :order 99)))

I'm still seeing the above TODO entry in Active Projects, even though my understanding of :and (:todo "TODO" :children todo) is that it should ONLY include things that

1. Have a todo keyword
   AND
2. Have children with todo keywords

and the entry in question fails # 2, and so should be filtered out of the group, but isn't.

Any ideas? Am I misunderstanding something here?
