I would love to have a way to see all completed items in the past day, week, or whatever so that in doing my weekly review I could see and remember accomplishments. (And it would have the added benefit, that if I accidently checked an item, and I can’t remember or didn’t see what I checked, that I would easily be able to go back and figure that out.)
Even just having date archived in the archive list, as well as sorting by date archived would be a vast improvement. As far as I can tell there is no way for me to extract this information.
