One item that seems to be missing, unless I'm just not seeing it, is the ability to put something on an agenda for a person. Many other apps do this through tags. So, I can make a "next action" and then tag it with Lisa or Kathry. Then when I see them I can easily look up any tags with their name.
And even more elegant GTD solution which I haven't seen any other apps doe would be to have an "Agenda" as one of the main categories in the bottom list.
Agendas are a very important part of GTD and need to be handled in some way
