For marking attendance or just reviewing which groups have been registered, etc., we would like to be able to sort the Guest/Host column to group parties together.

For an event happening this week, we had a couple accidentally register twice for each other. Sara registered for herself and June, and June registered for herself and Sara, but her payment came from Juniper and her registration was for June. We now have 5 rows for 2 people, and if we mark attendance, there's a strong possibility that we'll mark "attended" on separate guest/host sets, which will complicate reporting, especially if we refund one of the registration fees or change that registration to a regular donation, etc.
