I'm "invalidating" some items so I can use them as notes or non-actionable information. However, they'll get hidden when I hide completed tasks, and pushed to the bottom if I ask for completed tasks to be moved down.
Is there any chance we could mark items as "non-actionable", which would mean they don't affect the %complete, and aren't affected by sorting based on complete/non-complete?
Did you consider using notes for such kind of information?
Try 'nn' shortcut.
