Specifically, to be counted as processed, tasks need (at least):
- a major context, and
- a soft date or Someday/Maybe.
It should also include (as needed):
- 1-1 contexts or automatic delegation tracking,
- meeting contexts,
- action contexts,
- task notes, and
- a few next steps (if it is a project).
In Things, flag task as processed by dragging and dropping it to Anytime (left pane)
