I have a few active projects contained in a folder (The Big Project :) = the root-folder), organized in a couple of subfolders.
In some of this projects I’m waiting for an answer from somebody else, so I have tasks like “Wait (since 28th of March) for an answer from X regarding Y!”, tagged with “waiting_for” and “X”.
Well… right now I have 11 such “waiting_for”-tasks and they are clouding a little my perspective (pun intended :) on the remaining tasks of the Big Project.
I realized my problem are not the “waiting_for”-tasks - these get easily tracked (with a “waiting_for”-perspective) and the projects are reviewed regularly, so they don’t get lost - but the fact that the “waiting_for”-tasks are hiding a little the other tasks!
So I started building a new OmniFocus-perspective with this goal: Show me the tasks in all the active projects…
… within my root-folder,
… whitout (!) the tag “waiting_for” and…
… where this projects have at least another task then the “waiting_for”-ones.
Re-reading the article you sent I finally discovered how to make an exclusive statement (like “all tasks whitout the tag waiting_for”) so I was able to filter within my root-folder the remaining tasks from whitout the tag “waiting_for”.
What I still don’t get is avoiding the projects that have only one remaining task and this very last task has the tag “waiting_for”: I get the title of the project and no task underneath when sorting for projects or a place-holder-task with the name of the project itself when no sorting at all (this place-holder-tasks do not exist actually!).
So I’m a lot nearer now - thanks to you! - but a hurdle still remains: How to avoid listing projects that have only one remaining task when this task have the tag I excluded before?
