I guess, for me, the problem really lies in OmniFocus's filtering mechanism. When I click on my @Joe context, I want to see ALL tasks under that context by default, since it is a "special" (for me) context ("Waiting for", "Agenda", what have you)

To solve this, OmniFocus should either remember the filters you apply on a context-by-context basis, or allow you to apply a default filter for a context. In other words, I know that every time I click on @Joe, I want to see ALL tasks, nut just available ones or next actions. Why should I have to configure this every time, when otherwise I just want to see available tasks or next actions?
