In the attached image of a D&D 5e character sheet, you'll notice spells but not cantrips have a "prepared" button on the side of them. Now that TCE (Tasha's) has Cantrip Versatility and Cantrip Formula, a player can swap out cantrips on a regular basis. Having a prepared button on the side would be very, very helpful for the lowly wizard who just wants to make sure what they have ready for the day.
