Feature request: filter to show all projects _except_ completed
 

Don't know whether this has been suggested before -- bear with me if it has.

While wondering about filters in OF (ceterum censeo: the option to filter for "all" in context view should be brought back), it struck me that we cannot at this point remove just the completed projects from the outline.

At the beginning, this did not pose a problem. Now, however, I have several completed projects hanging around, distracting me. I would like to show all others, whether active, pending, or on hold, and forget about the completed ones.

Over the long haul, this functionality is needed, or else users will take to deleting completed projects, which sort of contravenes the idea of documenting everything you've done.
