I archive a list I call "Done (Week of xx.xx.xx)" each week. Sometimes I need to search for one I archived in the past, but the only way the archive is currently sorted is by name. Since I use dates in the name of the list, they get sorted by the first digit within their name (e.g. January is followed by October, since both months start with 1). So, that's not very helpful.
I don't think there's a way to sort it any other way, but would like to see another option. It would be especially helpful when I accidentally archive a list that I don't recall what I named it.
