I search for “not @done” all the time. I save the search, but that means I 1) have to save it in all of my lists, and 2) have to click on it to use it. I’m something of a keyboard fanatic, and looking for active tasks is pretty universal, so could we possibly add a “Not @done” filter (to the View menu?) that we could then assign our own shortcut key to (through OSX’s standard keyboard preferences)? This would save us from having to copy the search to every list, and make it easily to toggle with a keystroke.
As a more general request, being able to assign shortcut keys to any saved search would be even better.
And having always available common saved searches that were TaskPaper-wide, not just in a single list, would be even better than that.
