Great hack by Jan-Yves Ruzicka to introduce the concept of ‘tagging’ to OmniFocus. He leverages the saved search functionality in Perspectives to do that.
There’s one more thing I can do to make this process easier, and that’s set up a perspective. Perspectives remember search terms, so I can take a snapshot of this view as it stands, and use it whenever I need to refer to my high-priority projects. And, of course, if I do want to remove a project from my high-priority list, all I need to do is edit the notes field and remove the “@30000ft”. If you want, you could collapse every project ever and make sure that your 30,000ft high-priority perspective saves expansion, to give you an ultra-brief run-down of what you consider high-priority right now.
